Micro-Limit NL Questions

[aLittleFish]

I'm new to both 2+2 and internet poker and am looking for help. I recently started playing for real money on PokerStars where I deposited $50. With such a small bankroll I didn't feel like I would be able to handle any bad run of cards at the .10 / .25 NL game, so I've been playing the .01 / .02 NL tables. While I know this post is probably way below the level of most 2+2ers, I was hoping someone would like to share some wisdom with me. Mainly, what kind of hourly win rate is considered doing very well at such a small blind table and about when will I build a bankroll high enough to move onto the .10/.25 NL tables without fear of going broke on a bad run of cards?
