Well, I'm a sort of a newbie myself into this world of hi-fi but after reading a lot of articles on this I think I could offer some advice. On the amplifier side of things, I've always heard you're supposed to get an amplifier that's higher rated than the speakers to eliminate clipping, this translates into distortion which eventually destroys your speakers.
As for receiver brands, I've had good results with Denon never realized how crappy my other amplifier was, really opened my speakers up. I've heard people rave about the audyssey function too, haven't tried it out for myself but it seems like a good addition. On the speaker side of things, the speakers you've chosen are particularly small and would warrant the need for a subwoofer. The reason being, 3 inch to 4 inch driver's bass decreases in volume after 120hz -200hz.
If you're looking to stretch your budget on speakers look parts-express.com I've seen some well priced speakers on there. From what I can see on there, it's between the dayton mk402 and the BIC Venturi DV62si within your price range. When looking for loudspeakers, while this is not always true, if you spot push clip speaker terminals in a modern speaker, it's cheaply designed. You don't want that. Anyway, hope I helped you out.
