my first thought is
how do i get into this game?

first of all, its good that you reconize the player types at the table.

However, tightening up would be your downfall, and playing aggressive would be worse.

The reason you shouldnt be aggessive, is because they wont fold
so dont bluff, cause they dont care, aperently.

Basically you want to limp into every reasonable hand as cheap as possible.

When you miss, its check fold.
When you hit something, its check call
When you hit big, its check raise, or bet small-call raises...

when you win pots, act like you are the luckiest SOB on the planet.
when you lose pots, look confused ( how the .... oh lol, you had an ace )
