3 betting turn with TPTK and flush outs

I am trying to be selectively more aggressive with hands like TPTK.

1) Is the following a good spot?
2) Would you 3-bet this giving the history without the flush draw?

History: I am new to the table and have no PT reads on the villain. Recently I bluffed the whole way with K-high and he called down with a small pair.

preflop Hero raises UTG+1 with A[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/diamond.gif[/img], Villain calls in sb, bb folds.
