three handed play with an aggressive player to your left

How do I play this with a decent-sized stack? Specifically:

1) What should be my attitude if he plays back at me from the BB (on that hand and on subsequent SBs)
2) How often and with what cards should I play back at him from my BB when he raises on the button? Minraises?
3) Should I ever call his raise on my BB? Minraise?
4) Should I ever complete my SB, or is it raise or fold?

Basically, I find it to be really difficult to play here without good cards. I think I need a general attitude adjustment here because I've been getting a ton of thirds, and I know it's because of timid play, but I'm having trouble identifying specific hands where I make an error.

I'm absolutely terrified of betting more than 15x the BB or so on a reraise bluff, so I think I just need you guys to tell me when you do it and to shut up and do it then too.
