Like Ong Bonga said you should start a discussion on shortstacking, and also it will help you if you read and some articles about cash games.
There are also a lot of poker books for cash games that I think will help you:
Cash Games (How to Win at No-Limit Hold'em Money Games) Vol.1 by Dan Harrington;
Harrington on Cash Games, Volume II: How to Play No-Limit Hold 'em Cash Games by Bill Robertie;
Harrington on Online Cash Games; 6-Max No-Limit Hold 'em by Dan Harrington;
