QQ on the button vs. a LAG - How's my line?

[7ontheline]

I am on the button here - the preflop raiser directly to my right is a 60/20/1.5 LAG - very loose preflop, tightens up with each street. Generally seems to bet if not scared off. How's my line here? I did not want to give away the strength of my hand immediately, since I was pretty sure he would bet. The blinds were pretty tight, so I was confident they would fold if they didn't have a real hand. Should I have played this differently?

Cold-called so he wouldn't necessarily put me on a big PP. Mistake?

Raised here because with the coordinated board, I wanted to charge a draw and because I felt that a raise did not necessarily reveal my hand.

Should I have raised here?
