Questions about bankroll and moving up?

[shyturtle27]

So I've been playing poker pretty seriously as a student of the game for about 6 months for cash games and an additonal 3 months or so of SNG's. I've probably got about 30-40k hands at 6-max. I started a new bankroll back at the end of march of $200 and have played 10NL for over 10k hands with a winrate of about 5PTBB/100 hands. It's been MUCH better in the last 5k hands. I want to take a shot at 25NL. In my poker account I have about $425, I have a $150 rakeback check coming in a week, and still $125 in bonus to clear. From these three sources, can I count it all as my bankroll, just the rakeback and poker account, or just my poker account? I said I'd move to 25NL at 20-22 buy-ins. I have the confidence that I can beat it. Can I move up now or wait for the rake back?
