Yes lots of retrograde planets in your chart, including all of the 8th house planets apart form the Moon. Its important to remember that nearly half of people are born with a retrograde Pluto, and I would guess well over a third of people are born with Saturn retrograde. With Mars its probably nearer 10%, however, making it more of a rarity.
Retrograde planets aren't weak or bad, but they do tend to need more patience in terms of outward expression in the world. Some degree of difficulty can occur around making the planet effective in the world due to the inward orientation. Strengths of retrogradation include rendering the planet less prone to being swayed by collective and external ways of being, and more in touch with the core values of the individual.
With Mars I think this can mean checking whether things are getting bottled up, and I guess also with Pluto. Saturn perhaps needs more encouragement than a direct Saturn to risk trying to achieve something in the world, but when it does it is more likely to have integrity. These are only tendencies though.
The 8th house placement of these planets may add to their tendency to work more inwardly to some extent. To explain what I meant by 'rescuing' planets from the 8th, I'll say something about my take on the 8th house generally. The 8th seems to symbolise those experiences in which there is a fusion with another individual on a feeling level - an intimate sharing of oneself. Such experiences tend to draw out parts of oneself that have not so far been accepted by, and integrated into, the sense of identity - this can be for a variety of reasons, but generally speaking it is to do with a conflict of values. So when people describe the 8th house as the house of other peoples' values (opposite the 2nd house of one'sown values), the other person can be understood as ultimately being the other within oneself - the unconscious, which carries those things that clash with our consciously held values.
So we are confronted with our own unconscious, and the crises that are also linked to the 8th house ensue, as, hopefully does the transformation as the ego sheds its old skin to make room for the integration of new values from the unconscious.
Planets in the 8th house can be suppressed if we associate their expression with crises that we are unwilling to endure. Also, we may express them according to another person's values in order to maintain the fusion and thus avoid a crisis - i.e. we live out a part of ourselves through another to avoid the inner confrontation. A third possibility is that we experience a power struggle with the other over the expression of the planet, but do not yield on an inner level to the process trying to take place.
Rescuing a planet, I would say, is about being willing to yield in order gain true self-mastery, rather than avoiding the risk of letting go of the superficial and fragile control we currently have over our experience of that planet.
In terms of resources in your chart, I would say your imagination could be a great ally to you. The ruler of your 8th house planets is Venus, which is in the 12th house, and perhaps your main way into the watery realm of feelings is through Pisces, which is a very imaginative sign. Your beliefs and ideals could provide a sustaining and illuminating backdrop to this personal journey into your underworld (Jupiter in Scorpio in the 9th and Neptune in Sagittarius in the 11th)
My hunch is that you need to convince yourself that your intellectual defences (against the chaos and potential suffering of the feeling realm) are more rigid than is ideal for your well-being as a whole person. Then you can more easily process the feelings and reclaim your power.
This very much parallels my own journey, so I know how hard it is. I certainly haven't managed to put all this into practise myself yet.
Just to clarify something, as well as being strongly Aquarian, Virgoan, Piscean and Libran, you are also strongly Scorpionic due to Jupiter in Scorpio, the 8th house emphasis, and the angular Pluto.
One more thing - that stuff you were reading about Sun in the twelth house and other stuff like it is not helpful and not astrology as it should be, in my view. An interpretation shouldn't kid you that your life will be easier than it will be, but it should never deplete your sense of personal power with which to shape your life.
