Being 5 handed makes our hand seem stronger PF. My first response would be to raise this PF... this should give you an idea of where you stand - as he will (or should) only cap with hands much better than ours - and will cause us to play much more passively throughout the hand. I personally like to maintain agression when OOP.

I would raise the flop given the action. His C-bet doesn't mean much. Most TAG's will c-bet any and all flops after a PF raise. We certainly have 8 outs, and probablly closer to around 10-14 (although we're not sure which ones exactly).

We will expect him to call the flop raise (most hands will for 1 more bet). And would fire again on the turn.
The river is where I feel the true question comes - if he calls us down to the river... do we fire again with the chance the A-high folds?
