Just move up when you feel comfortable. You've got about eight billion buyins for the 33s, so why not move up to them first (you really should start 4-tabling at least.. giving up money otherwise), and, if and when you feel comfortable, move up to the 55s.

If you do poorly at the 33s at first, move back down to the 22s to build your confidence/bankroll.

It's not like "moving up" is some irreversible move. You can always move up/down at any time.
