PF calling range against LAG player

[swifttarrow]

I'm trying to move up into the 15/30 game at the Oaks; I usually play the 3/6 and 6/12 game, of which I can normally beat. My second session playing 15/30, LAG player two seats to my right, game is a little maniacal. I've seen LAG player 3 bet ace 6 offsuit, j 9 suited, jq offsuit, qq, 88. He's capable of betting air all the way to the river, but shows down the goods ~80% on the river.

In this type of game, am I looking to play tighter or looser? Game is a complete mix of tight and loose players, but for the most part, the average number of players to the flop is 4. If LAG player 3 bets, what's my minimum calling range if I expect at most 4 players to the flop? How does this change if I have a donk two seats to my left who likes going to war with LAG?
