check out accessories4less for good deals on AVR's...
For the speakers I would go with Ascend acoustics...
I went with 340se for the front sound stage and 200se's for the surrounds... I believe I spent around $1100 on them, but I auditioned so many sets of speakers and they were leaps and bounds ahead of all others in the price range...
You can go with any setup though, I just setup my brother in law with 200se's all around front and rear with an HSU STF2 sub, and ONKYO 525 avr it sounded great...
For your budget I would do this...
STF2 sub $320
Ascend cbm170 fronts, 340 center, and 200 surrounds $850 {when you buy all at once}
and
marantz sr5002 receiver --has preouts, looks interesting for $250 orig price $800, has second zone too... but there are tons of avrs in your price range...
the preouts will leave you the freedom to upgrade to a separate amp to power your front three in the future...
I have heard the vtf2, very nice sub especially for the money, and own the 170s, 340 and 200's they are also so far ahead of anything 3 times there price its like stealing... The only thing I never heard was the avr, but Ive heard marantz and they are usually nice...
Then for future upgrades add an XPA3 Emotiva amp for your fronts, and a second vtf2 sub...
