Yes. I think the best inquiry would be for any advice on resources for learning how to read aspects. If chart reading is a language, then I'm at the point where I know most of the words, and the rules of grammar, but am still slow to string together the entire sentence with fluidity.
To know what the aspects of planets mean you of course need to know what each planet represents. After that you learn about harmonious, tense and neutral aspects.
Harmonious:
Conjunction (Two planets max. 5° apart)
Trine (120°)
Sextile (60°)
Semi-sextile (30°) (Less powerful)
Tense:
Opposition (180°)
Square (90°)
Semi-square (45°) (Less powerful)
Sesquiquadrate (135°) (Less powerful)
Quincuncx or Inconjunct (150°) (Less powerful)
---------------------------
+ Conjunction combines planets like mashed potatoes...Or a stew.
+Trine brings the planets together in an easy combination that makes everything smooth... (Natural and automatic)
+Sextile are kind of like Trines, but the natives are more aware of these 'talents' that the aspect gives them. It shows potential for use of these energies wisely. Also communicative and relationship-friendly aspects. (Conscious effort required)
Semi-sextile reveals opportunities that seem to go unnoticed.
- Opposition is unsure and wavering. We feel torn and we seek
interactions with others to learn about our internal struggles. As we learn, we're more willing to negotiate.
- Square creates a lot of tension and makes us run into countless of obstacles. Often these aspects are more difficult when we are young, as these aspects force us to grow and learn our lessons. (Demands action)
Semi-square blocks your path and pulls to back instead of moving forward. This teaches you persistence and patience. (Makes you consider things twice)
Sesquiquadrate reveals an area of frustration or disappointment. This aspect is asking you to chill out and wants you to develop some endurance, persistance and patience to avoid the overwhelming feelings of impatience and resentment.
Quincuncx/Inconjunction ("
Integration") wants you to change something/make an adjustment in the two houses where the planets sit. It will teach you to either bend or break and will challenge your intuition.
...Use the information and make your own interpretation. Does your Mercury Trine your Moon? Then you could say "
My 'thoughts and/or communication collaborates with my emotions and/or instincts." but you'll have to know the question or topic it falls upon to make it more exact.

Also, I'm curious as to how best to interpret signs in houses. Does it matter how much of that house is influenced by a sign/if so, how would I interpret having two signs influencing one house?
That depends on which system you use. Some people use the Equal House system which allows each house to have exactly one sign.
I use the Placidus system which I can see from your chart that you've used as well... I don't think you need to focus on how big the houses are, of course other people might say otherwise, but I just look at where the house begins and where it ends. Also, some people believe in cusps others don't. If you have an Ascendant that's 29 degrees in say, Sagittarius, then you might notice that you have many traits from the next sign; Capricorn. The same with planets.. The higher the degree of a planet is, the more mature it is and is close to being fully developed.
I hope it was helpful. :3
