How's my line? Nut draw with overs

[DP388]

I recently changed gears and have bet/raised the last 3 out of 7 hands with no showdown. Villian has made some loose calls pre-flop, but is relatively straight forward post flop. In general the table is playing pretty tight as we are near the bubble.

Full Tilt $24 - $26K guaranteed. 180 pay, 186 left.

I think there is certainly a case for folding pre-flop since I've been active, so I'd like to hear opinions about that.

Also, what about a flop shove? (3800 in pot and my stack was about 8K)
