Two Confusing Hands- Live 1/2

Villain in first hand is on mega-tilt. I took his entire stack when he went allin with a baby flush and I called with the nuts. He is resolved to "get back his money" and has been making bad plays the past half hour. I am his "nemesis." Stacks: Villain $200 and I cover. There is a straddle to $4. Raise amount preflop is standard at this table for straddles.

2 folds, Hero raises to $20 with AQos, Only caller is Villain from SB.

FLOP: 46Q All hearts
Villain immediately goes allin for $180 into a pot of $46. I do not have the A of hearts, but I sense I am ahead. Are we calling this?

Villain in the next hand is extremely intimidated by me after I laid down AQ face up to a nit on a 24Q board(guy showed 22). After he says "Remind me never to get into a pot with you." Villain is a solid TAG and this is his 2nd raise in ~25 hands. He has $200 and I cover. Table is very loose at this point.

1 fold, Villain raises to 6, Hero calls with Qc8c, 3 other callers.

FLOP: 9d9c2c (Pot 30)
Villain Checks, Hero bets $20, Villain only Caller
TURN: 3c (Pot $70)
Villain bets $50, Hero??????

I'm really not sure what to do here, and it is never fun to get all my chips in drawing dead. About half the hands I put in villain's range led me to believe that I might be.

Hand 1: my initial reaction is to say call. I would look at your percieved image of villian (mega tilt) and how he percieves you (i want to beat this mother ******!!!). It could easily be an overbet with 7-7+ or a big FD. I think mega tilt would check his monsters, in the hopes of keeping action in, not forcing it out (assuming most mega tilters usually don't think at multiple levels).

Hand 2: this one is kind of hard, but i imagine if he has A-9/10-9 and you call a big turn bet, he is checking his set or leading out again with a higher flush. Though looking at this calling the turn makes it very difficult to surrender this hand on the river, regardless of his action. I might go for a minraise here and see if he shoves/folds/calls. If he calls/folds, you are good i think. And if he shoves you are beat most of the time, i think (especially if he was being serious when he said he didn't want to play against you). $50 extra on the turn is cheaper than $65-70 on the river.

And trips probably isn't going to pay you much more on the river, besides the smallest of value bets on the river (not worth it to let him try to draw to a FH/ higher flush). Though Kc-9x and Ac-9x would likely shove the turn and you have an edge over those hands making it profitable to call ((7 clubs+11 FH outs)x ~2= 36% at best), that is the only scenario i can think of where calling a turn shove has you ahead or even drawing live.

Question: how often would this board tempt a player to bluff (suspecting opponent is afraid of clubs because of his flop bet)?
