Hand in Super Thursday $150+12 NLHE... what do you do?

[allenciox]

There are about 50 players left out of close to 800 starting. Your table is playing quite tight, since you got here, which was not long ago. You are in the cutoff; you are the second high stack at your table with T26000, while the button is third high stack with T23000. Small blind has ~T6k, while big blind has ~T8k. Blinds are 300/600. You are dealt 8d9d, it is folded to you.

1) What do you bet (or do you fold)?

2) Assume that you bet 1600, the button raises you to 2600, and everyone else folds. What do you do now?

3) Assume that you call the raise, and the flop comes 9h 6h 2s. What do you do now?

4) Assume that you check to the raiser. Now he moves his chips all-in. What do you do now? Also, what do you think he has?

Results later... feel free to critique my actions, which are above.
