In the last hand where you have TT, I think pre-flop you could use a bigger raise given the stacks. Bringing the PFR size to 3bb in general I think is advisable when you are 100bb deep, though in this particular situation I don't see it would have gotten you any more folds. Just something to consider, when play is deep-stacked, use bigger PF raise to make those more marginal hands have to further consider if they really want to have a look at the flop.
After the flop I think you could reraise all-in instead of 3! to 3x, which, if villain just called, would leave you about one 1/2pot sized bet remaining.
The flop is so wet, even with flopped middle set there are plenty of cards you don't want to see on the turn, because you know Villain is never going to fold to your 1/2 pot sized bet, and therefore in that sense think your hand "could" use some protection.
Imagine seeing for instance a
on the turn after opponent just called your flop reraise. You are pretty much forced to shove it here, or face a fold/all-in decision. While probably you're never (and neither am I) folding 2nd set in that situation, it's better to leave those nasty decisions to the villains.
Long story short, if you are committed to the hand as you were here after getting raised on your flop bet, and the pot is already around 20-25% of your stack, just blast the horn and announce the ship is departing. A set of eights surely wants a ticket to value-town.
EDIT:
I finally bought Flopzilla, and while am definitely not proficient with it, here's a range I think could both
a) given the stack sizes, call your small-ish PF raise and
b) raise your small-ish flop bet
It is at 29,3 % equity against your flopped set.
This range can almost profitably call your flop re-raise with the 29,8 % pot odds.
If you shove instead of 3! to 3x, villain needs around 44 % equity to call profitably.
