I wouldn't play any play money online, just start at the micro-limits to get a feel for the game. Once you have a decent bankroll move to the mid-stake limits online. Watch videos and read the Dan Harrington books, either tourney or cash, whichever game you play, and check out the 2+2 site for additional info. Also play low-limit sng's online $5 and under starting out.
These are my suggestions, good luck on the felt, online or live!
