Chipleader with 99's in the SB

[tiger7210]

I know I misplayed this hand both preflop as well as post flop and would like to get some comments to verify my 2nd guessing. My relevent reads are villain is a loose fish (typical for a $5 tourny I guess), and CO was fairly solid straight forward player. At this point I have a huge chiplead in the tourny by close to 30K chips and have only shown down solid hands. My thinking is I should have raised more preflop to try and win the pot right there being out of position postflop. My 2nd mistake I believe was not reraising him on the flop which is where I think I played it too weak. I put him on the flush draw which is why I put him in on the turn. Please comment on any or all streets. Thank you.
