$5/10/20 KdJd OOP with top pair

Some context:
Hero's second time playing the $5/10 (which always plays $5/10/20). The first time was only for a couple hours no hands of note. Second day has also been only a few hours and most of the table has been playing pretty tight, fit or fold.

Villain was there both times and is a tight euro pro looking dude in late 20s/early 30s. Other regs at the table teased him more than once about how tight he plays.

I've been attacking the limps of the older rec lady on my right a good number of times, nothing out of line though and have folded twice vs a resteal in that spot.

OTTH:

~$2500 eff

HJ limps, hero in CO raises to $100, V BTN 3bets $325, hero calls, all fold

Pot $700

Flop K82r

Hero check, V bets $175, hero calls

Pot $1050

Turn Qs bringing in backdoor spade draw

Hero check, V bets $475

Hero??

Input on all streets welcome. Should we ever consider raising the tiny flop cbet?
Are we ever doing anything but calling pre flop? Any merit to limping behind with only BTN behind and weaker players in blinds with the straddle on?

I don't know villain well enough to know if he would normally continue larger with bluffs and value on the turn.

What do you all think?
