Cazique's advice was really good. Try to chose a table/seat that has looser/weak players to your right and the tighter players to your left. This gives you position when you are raising fish preflop bets/limps, although with really loose players 40+ VPIP you can reraise them OOP and still take down pots easily. Below is an example of beating on weak LAGs from a few hours ago (although you should stick with this type of hand while in position).
poker stars $0.02/$0.05 No Limit Hold'em - 5 players
Hero (SB): $5.00
BB: $5.32 (31/0/0.3)

The range you should stick with are your usual pocket pairs, broadway, and suited connectors. With this range and you in position it becomes a murder on the limping LAGs when you raise them preflop. Also pay attention to their fold to cbet percent. If you're up against a LAG (or anyone) that never folds, don't bother to try
bluffing or cebtting with total air, you'll lose money fast.
And finally, when playing against regs, keep the pot small unless you have a monster hand.
