A-K suited, Party 30-60 full, indecision on all streets

[raconteur]

I open utg with As-Ks, its folded to a player in mid position 25/19/1.64/525 (im in the new toy stage of using pokertracker), who threebets, and its folded around to me, and I call. The flop comes 9s-8s-7c, I checkraise and get called. The turn comes the 3h, i lead, get raised, and call. The river comes the Kd. Lead/call, check/call, check/raise? I'm also undecided as to whether I should have capped preflop, or simply led the flop after not capping pre, or adopted one of several alternative lines.
