raised 99 with Ace on flop against pfreraiser

[friends]

Prima, 0.5/1

Average VPT 21-23%

Hero is on UTG with 99.
Button - 13/6/2.5 acc. to 250hands.

Hero raises, everyone folds, button reraises, hero calls.
Flop (7.5Sb) - 2 3 A
Hero?

2 question:
1) Should I cap preflop (to represent lately stronger hand)?
2) Should I continue on flop (bet or check-raise)?

Possible button hands: AQ, AK, AA, KK, QQ, JJ, TT.
I am beaten anyway, but the probability of KK, QQ, JJ, and TT is about 30%, TAG may fold them with Ace on flop.
