Your Powerstroke options are a good choice. They'll cut out some excess overtone that you don't want. You'll really have to try them out to know how they're going to respond to your kit. I would go with Remo clear Ambassadors for the bottom. You don't want to completely kill overtone because you'll risk your toms sounding boxy.
As for cymbals, you're going to have to spend some money to get quality sound. There's no way around it.
