Dude,
First off, don't play on www.pokerroom.com, call me crazy but I don't trust that site anymore. I was in the same boat as you, playing for play money and I was raking it in, I was getting great hands. Switched to real money and the hands I received were terrible, I mean really bad. I lost 140 dollars on poker room.
Then I found www.flopturnriver.com and started playing on empire poker, and I am now making money. I have balanced my initial loss and am in profit, and the bonuses are cool.

Second, they money you made with play money means nothing. Its so different playing for real money.

Third, read everything on www.flopturnriver.com and memorise the outs table. Its essential you learn the mathematics behind the game.

Later slick....
