AA out of the BB

[vhuntd]

Wasn't sure what to do with this hand

live 3-6 game - EXTREMELY passive table except MP3 and CO who aren't overly agressive but will usually bet their better hands as opposed to the rest of the table- usual preflop standards for lowlimit live play. 6 limpers (including MP3 and CO) to me in the BB and i raise with two red aces.
FLOP: K(spades) 2(clubs) J(spades)

I check hoping to check raise. MP3 bets and CO raises. I've played with the CO before and I am almost positive that he won't raise in this spot with worse than two pair. He looks like he has a reasonably strong hand but not a lock so I put him on two pr as opposed to a set.

MP3 i have a pretty good handle on and I put him on either a K or a J - haven't ever seen him bet a draw. It's folded to me and there are two tight passive players between me and MP3. I just call for a couple reasons.
(1) I expecting the other two between me and MP3 to fold anything that isn't an OESD or a four flush.
(2) I think that I'm behind CO
So the two between me and MP3 fold and MP3 calls.

TURN: 4 (diamonds)

I check MP3 checks CO bets and we both call.

RIVER: 8 (hearts)

Checked through - CO tables K2 and takes the pot.

How's my line here.
(1) should i have bet the flop given the passive table?
(2) should I have 3 bet the flop despite my strong read that I was behind? (I put the CO on KJ)
Any other mistakes that I made?

Thanks.

I would have.

If you were confident in your read, I think cold-calling the flop and calling the turn was best.
