PLEASE HELP ME!!

I'm back and forth on what to buy to upgrade my old receiver, front speakers, and center channel. Recently ordered a new sub, but am running a 4+ year old Pioneer 7.1 ch receiver and some jbl towers with CV center channel. I'm not rich by any means, so I want to make good choices as I'll be stuck with them for a long while. I've done a lot of research into pioneer elite and onkyo receivers, and as far as speakers i've looked at kilpsch, deftech, and b&w's. My question is this, if you had a budget of 2,000.00 and wanted to add all 4 pieces at one time (center, 2 towers (fronts), and a receiver), what would your breakdown be on brands/models to fill the bill? I've gone back and forth on spending more on the receiver (say 800-1000) and a little less on the speakers, or possibly getting a better receiver and center and going with a nice set of bookshelfs from b&w (600.00) instead of the higher dollar and possibly lesser sound quality towers that are 600-800+ pair. Anyway, your suggestions for any and all of the 4 pieces would be greatly appreciated. Worse case scenario I may just use an existing piece i already own in order to get better quality on 3 of the items. Ideally I'd like to buy all 4 and forget about anything except blu ray disc purchasing for another year or two.
