5-10NL AKs tough spot ... can yo do better?

[PokerForMath]

I am playing 5-10NL on full tilt. I have been playing aggressive and 3-betting a lot. I have a VPIP > 20 and pfr of about 17% (same as my previous post if you saw it).

I have AcKc utg and pot it. I have about $1000 in front of me but have been up and down this sesson. Folded to SB who 3-bets me. He has me well covered and is TAG and has not been playing back at so I elect to call and dump it unless I flop it good (mistake?). Flop comes

Js Jc Tc

There is 280 in the pot. I have 940 left and he has me covered. I think it is highly unlikely he would 3-bet me with AJ, so the danger hands in my view are AA, KK, QQ, possibly TT, but I doubt it. I am even money against everything but TT and in fact am even money vs JJ but think he might lay down AA or KK but not AJ, so that's why it's significant that I don't think he has it.

He bets out 100. Huh? What do do? I raise to 460 thinking I have fold equity and an insta call if he pushes. He pushes.

Questions: Is this a good line? Are there better lines? Is there any basis for just calling on the flop? For 4-betting pre-flop?
