Shorty,
I'm short too, maybe an inch taller than you are. I've flown several types of light aircraft and passenger turboprops without too much difficulty. The only one which was a really BAD fit was the C172, far too spacious, legs too short, arms too short, couldn't see over the instrument panel, you name it!
Don't agonise too much. You've heard from enough fellow shorties here to know that you'll be fine in the height department and if you continue to make an issue of it, you might just give someone the opportunity to agree with you at a critical stage in your training/career.
