I agree with Matt's advice of putting it outside year-round. It'll be a lot healthier that way.
Granted, if you get strong fluorescent lights you can keep it indoors, but VFT's *require* dormancy every year, so if grown under fluorescents, helping them go dormant every year (especially being in a zone 10, as I *think* you are) can be a real hassle.
As far as repotting, if you are going to - mid-growing-season is not the time to do it; you want to repot just as winter is giving way to spring. Repotting puts VFT's into shock because you disturb the roots and they stop growing for a time. You don't have to repot at all - it looks like it's already in a 50/50 mix of peat and perlite, which is exactly what I use. You'll want to change the soil it's in once a year (or every two years at the longest).
Pot size is fine for that VFT right now, but whenever you do repot it, I'd get a pot that's about 5" diameter and 6" deep, with drainage holes, and put it in a 1" deep tray (you can water at the tray, you rarely need to top-water).
Most importantly, read these when you have time:

Good luck! Keep us updated with pics and all that.
