Yeesh, a Yamaha and Klipsch combo has a very bright sound. If you can live with that, you will be fine just using your receiver.
If not, and you still want a power amp, then I'd recommend a B&K or Parasound. Top-shelf internals and build quality and sound quality.
Good choice with the SVS PB10 sub, but you probably will want to step up to a 12 with those monster front speakers.
Oh, and don't spend a ton on cables. It really ISN'T necessary. I've worked with electrical physicists and in their LABS they use Radio Shack gold cables. They said most of the high-end cables "high-end features" are just marketing gold. Affordable quality cables usually sound just as good, if not better, than the very expensive brands.
Right now, I'm buying bulk cable from bluejeanscable.com and terminating them myself. Excellent price for the quality you get. Just FYI.
