Wow, lots of good advice here Dana! There sure are pros and cons to most things, and acoustic vs electric is certainly on the list. Personally I chose electric because of the music, but I have an acoustic too, it typically has more dust on it
Muscle memory is a big one to remember, practice as slowly as you need to in order to be as accurate as possible. Small hands might slow you down in the beginning or maybe you will just play a bit differently. But if you are enjoying it, I expect it won't be a problem. I had a hand injury similar to Tony Iommi (have you listened to Joe's Pickup Radio show on this topic?), I have to play differently than everyone else...but I still play!
I do hope your teacher teaches to YOU! Not to everyone else that is not in the room with you. Teaches to what your style might be, your taste, your ability and pace. You're paying for it, get your money's worth, it is so worth it!
Have fun.
