I don't like the blind defense with 76o. You end up in situations on the flop which are not easy to deal with to say the least. If you must defend with 76o, I would 3-bet, it is simply alot easier to play the hand afterwards (though it may seem spewish, but paying .5BB to make the hand easier is +Ev as you are not likely to make drastic mistakes that cost 1BB or more, conversely it can be argued that the reason to play a certain way is not soley based on avoiding bad situations, but for a non-pro as myself I would rather avoid the tougher decisions for now).

As played, the flop c/r is difficult to gauge simply because you don't include as to how you balance this out. Do you sometimes fold you hand if you hit bottom pair but the board is more coordinated? Do you semi-bluff c/r? What about with top pair?

As played the turn is fine, but more importantly, the river call imho is absolutely mandatory. You may win this hand, but the most important piece of information at this showdown is whether or not the villain bets scare cards. The Tc completes both straight and flush, I really doubt villain has KJo here, he basically needed to put you on a set to make this play worthwhile (otherwise he is losing bets on the turn). If he backed into the flush, straight or JT and KT, it helps us but not as much as it would if he had a pure bluff or a weird AK in terms of understanding his playing style and level of thinking.

Alternatively, I would actually opt to check/call this river for the reasons stated above, as well as the ability to induce bluffs on this river, from hands that will try to represent a completed draw, to lone J or K, to desperate bluffs, and given the read, I am quite sure that he will bet on this river greater than 50% of the time when checked to (obviously hes betting his good hands, but he will raise your hand as well, not to mention, he might check behind a something of weak holding, but the aggressiveness of the villain described by OP makes this unlikely, why? How often do you encounter an aggro preflop, then goes passive postflop player?).
