By the way, there's some confusion with the opening theme. Should the first notes be played with the D# on the beat like a sixteenth and then the E for 3/16-notes, or should the D# be played earlier to make the E for the whole 1/4? I prefer the first option, the second sounds a bit too "naive" (can't come up with a better word), while the first option makes the theme sound more like it should - like a serious statement. What do you think?
Don't do K310 as your first sonata. It is one of the most difficult ones, play some other sonatas first so that you get the Mozartfeel.
