AKo flopping nut straight with 2 flush cards on board, how to play?

[binki]

This was a B/M game. I can't see very well so I sometimes have trouble in these games with boards and reading players or even seeing the action. I am sitting in the 5 spot so I am good for the board but not the 3 and 7 spots since I can't see them. Only 7 is in the hand of these two.

I have AKo all black and the flop is TJQ with 2 hearts, 5 in the pot and capped preflop (I 3 bet, seat one, the maniac, caps). I am the button. I figure I am the 2/1 favorite or so, correct?

Post flop it is checked to me and I bet, everyone stays.

Turn is a black 8 and an ep bets and I raise, still 5 in the pot as everyone calls.

River is a blank, checked to me and I bet, get 3 callers. One guy shows J9o and another 86 hearts. Maniac folded after I bet. Others were somewhat calling stations.

I can't think of any other way to get more money in the pot.

Am I right on the odds post flop?
Could I have done anything else to get more into the pot?
