A few thoughts on your Saturn transits, possibly more optimistic than I should be, but still rooted in logic.
When Saturn in Virgo opposes your Moon, you might be able to cut through some of the emotional fog of your Piscean moon, yet at the same time you might face emotional issues that show you emotions aren't so intangible as a Piscean moon would like them to be! Moon/Saturn, although quite different, do have a "less-than-sinister" relationship. Remember these two objects naturally oppose in the zodiac, as the rulers of the MC/IC axis. Even the zodiac itself shows their cooperation, and Saturn does a wonderful job in firming up the fickle Moon's nature and keeping her grounded in reality. I wouldn't worry yourself too much with the transit.
Saturn square Mars will be highly dependent on how you have integrated the Martian principle in your personality. I went through this transit back in 2001, yet the upper square to Mars is also a t-square my nodes and an opposition to my Sun, so it's hard to get a clear picture of what was actually a part of the Saturn/Mars square and what came from the other two aspects, both far more powerful. For me, part of it was a time of wreckless martian fun. Unlike my usual self, I spent that time partying, not giving a ****, and doing what I felt like. Saturn set me up with a short-term high-paying job in the months before, then made sure I was jobless for a good 9 months, and I blew every last cent of the savings! It was fun, but not like me. Obviously, it was a needed lesson, yet it did take a good year or two to relearn how to be responsible. See, I've never been the loose type, with Saturn as chart ruler and Virgo as strongest sign, the conflict of the square had the purpose of trying to break my out of rigidity. After the transit was over, a Mercury/Venus conjunction during a Mercury RX cycle happened close to my midheaven, which coincided with accepting a job offer resulting in a paycheck coming just a few days before rent was due, which I wouldn't have been able to pay otherwise. The period of this triple-hitter transit was by far the most daring period in my adult life yet, and I would imagine it would have been downright dangerous if my nature was other than that of reserve and caution. Regardless, Saturn/Mars are very different objects, and do tend to be a very conflict oriented pair. It is seldom these two can butt heads in a stress transit without something unusual happening -- They are just naturally at odds! You would probably be wise to cast a chart for the exact hit (or all three hits, if saturn RX's over the 90 degree point) and see what other interaction happens. Don't forget to check the transiting sky conditions, as well as all the other transits which will occur along with the Saturn/Mars square(s). This will give you a more complete picture of the energy of the transit. I tend to interpret cyclic transit aspect charts, especially the "big 4" (0, 90, 180, 270 aka upper square) much like return charts to get a better idea of the transit's potential.
Assuming you are content with your individuality, and express it in a healthy manner, the new Saturn/Uranus cycle for you may help you solidify some of your Uranian traits. It could also help you figure out which Uranian parts of yourself you wish to solidify, versus those you wish to drop because they no longer do you any good. Remember that the conjunction indicates the start of a new cycle, a birthing of sorts, and not the conflictual energy of the 45/90/135/180 angular transits. For this reason, conjunction transits, while very powerful, seldom have the real difficulties and struggles involved in the conflictual transits. For example, the last transiting conjunction of Saturn/Uranus in the late 80s saw the forming (Saturn) of a number of high tech companies (Uranus) including some of the more major players in the computer industry today. Fastforward to around 2000-2001, which puts you in the midst of the first (lower) square of the cycle, and you have the "dot-com implosion" which put a huge dent in the high-tech industry, a good example of how the conjunction starts new things and the conflictual transits can cause some real troubles for what was started.
I am unsure about the opposition to the Venus/Chiron conjunction, honestly
However, Saturn crossing over your ascendant, you should be looking forward to, plain and simple. While the Saturn Return around age 29 brings you into true "adulthood", it is said that you don't "have the keys" until Saturn has made its second cross over your ascendant. Several pieces I've read on the Saturn return indicate this, yet I am not old enough to have personal experience. It is said that after Saturn crosses your ascendant the second time, which of course will be between your first and second return, you have finally entered the emotional maturation phase, without so many material/worldly restrictions imposed. Saturn transiting through the first house is also useful to work on the image people see you as, and bring it into more socially acceptable terms, at least outwardly.
In short, many people fear Saturn's transits more than they should. While Saturn can bring tough lessons through restrictions and difficulty, remember patience is his big thing, as well as success, stability and responsibility. Saturn seldom brings on the sort of grand insanity and beyond-your-control situations the outer planet transits can encourage, and almost always shows you new and more workable ways to be who you truely are. It's all in your attitude to Saturn's teachings, and how much you kick like a screaming baby and block the energy. It's also worth mentioning Saturn transits are _alot_ easier if you're conscious of the process, especially considering Saturn (along with the Sun/Moon) are the three planets of consciousness, forming the central triangle of the enneagram and thus the planetary representation of the trinity of human consciousness.
Also, one planet seldom works alone. Sure, one planet usually forms the "trigger", which shows up by forming a very tight orb aspect in a crisis chart, but there's always another factor that the situation is bouncing off of. For this reason, it's wise to check what transiting (real-time sky) aspects occur to Saturn while in tight orbed transit to a natal object. A major aspect between transiting Saturn and another transiting planet indicates the other transiting planet is making a transit to the same natal planet Saturn is transiting. These sort of situations can be far more powerful than a one-on-one transit to your natal chart, and they also modify the tone of the Saturn transit.
Anyways, just figured I'd offer some input, and again do my often-practiced job of trying to convince people to look at ole Saturn with less gloom and doom and a more positive views of the gifts available
After participating in the earth-shaking unpredictability and high pitched shrill of Uranus transits, the foggy bottoms of Neptune transits, and the sheer power and destruction available through Pluto transits, one can be contented with experiencing the transits of any object you can see with the naked eye... Not that the outer planets are all bad news, but they can be much more difficult forces to encounter.
