One thing to consider is that he really is just hitting a lot of hands and not nessicarilly "floating." I've gotten into trouble assuming that somebody is bluffing a lot when they've actually just been a card rack for the past hour.

If you have good reason and evidence to believe he floats a lot, then these all look pretty standard except the last hand, I am not a big fan of the turn shove unless you really think he would call with worse, the flop didn't even contain a flush draw and the turn was pretty shitty because it completed a few two pair / straight combos as well as now losing to TT. I would've checked the turn and probably folded to any substantial river bet.
