I appreciate all help and suggestions...I will be plugging my Macbook Pro (wirelessly) and PC into the system...
I can't advise you on your bass and system needs as I am a noob to the Audio scene, but wanted to chime in regarding the wireless element of your setup. Are you planning to have an Airport Express in the mix?
If you haven't yet considered this, then I must highly recommend it. As an owner/user of an AirPort Express plugged into my receiver, I love being able to stream my entire iTunes library over my living room sound system, and control it all from my iPhone via the remote app. The best adjective I can think of is
badass.
Of course there are other wireless solutions out there and you may have already decided on your method, but if not it is definitely worth consideration.
FWIW, You can get a refurbished one from Apple for $85 and it carries the same warranty.
Good luck with your system!
