Defending against a LAG raiser-- Please evaluate my decisions

[dneedle1]

Very early in day 2 of a major live tournament. I'm in BB with big stack 85k with each round at t 2,200, so I'm in good shape. Villian, a LAG pro, has about 45k, and is raising 1st in with any 2. He raises in mp. Folds to me in bb with QJ suited. What do you do?

Flop-- 6 4 4, none of suit. What do you do?

In the event, I checked, he bet about 3k, I raised to about 12k, he called.

Turn is a jack (top pair)-- what do you do?
In the event, I c/c a bet of around 10k

River is a third 4. What do you do?

In the event I c/c'd his all in.
