Repotting is very easy and not bad for the plant, just wait until it is close to being rootbound, prepare the new larger pot half full of good soil, tip the old on eover suporting the stem between your fingers, tap sharply on the bottom of the pot, it shoudl slide right out, and you can plant and backfill around it.
Changing light conditions is stressful, and a young plant shoudl be under at least 18 hours of light per 24 hour cycle.
In my signature there's a really useful set of instructions I wrote out of pure boredom.... haha... enjoy!
