I'm fine with not capping pre-flop. Sometimes I cap and sometimes I don't. Certain players wil fold for two more pre-flop on a Button steal, and certain players won't. I'd make my decision on whether to cap or not based on (1) perceived opening range, (2) likelihood of Button folding for two more, and, as important if not more so, (3) how I think my cap would influence the flop play -- i.e., if I knew SB would always lead after getting called (and Button didn't cap most everything he steals with when 3-bet), then I'd rather SB have the flop lead. If there was a decent chance that Button would fold to the cap, I'd fire away.

I play it the same post-flop. I think I could make an argument for folding the river when it blanks - looking at this hand alone - but I think it's worth the BB to see a showdown (and almost surely lose) then play the hand as you did and fold the river. This sounds a bit goofy as I write it, so I'll think about it a little more.
