A great receiver for you would be the Yamaha RX-V663:

I am told that it can be had for about $400 or maybe even a little less. I, however, have not seen it that inexpensive.
As for speakers, it is probably best for you to go listen to as many different speakers as you can in your price range. The reason for this is that there is no such thing as a perfect speaker, and you must decide what combination of virtues and vices are important to you.
SVS makes great subwoofers, and, I am told, their other speakers are good too, but I have not heard their non-subwoofer speakers. Here, though, is a link to some in your budget (assuming you can get the price that I have been told you can get for the Yamaha above, and not including shipping costs):

Unfortunately, I doubt you will be able to audition these speakers without ordering them, as SVS is a "factory direct" sort of company.
Again, I recommend that you go audition speakers and buy some that you like.
For speaker wire, you can buy something very inexpensive. Take a look at:

I would not buy the Bose. Not at any price, if I had to keep it and could not sell it.
