I've been lurking here for a while, but I'm hardly an expert,

I would like some advice and guidance... so this is what I currently have:
Elite VSX-94TXH
Klipsch Quartets & KG's + a Klipsch SW-8 (7.1)
OPPO DVD player
I'm 60% HT, & 40% Music, but want to switch that around. My plan is to ease into this gradually, I can't afford to switch out everything.
So I'm thinking of starting by replacing the Quartets with some VSA VR-22's and keeping the Elite (since the VR-22's apparently don't require a lot of power). I might add an amp anyway though, so please advise here too.
I'd also like to upgrade my SW, (not sure with what yet, possibly the Rythmic F12) with one geared more towards music. I also might entertain two subs based on what I've read in the bass circle.
For music, apparently I should use my Main pre-outs to the sub rather than the LFE (or possibly do both depending on the sub I choose)
My main question is how do I hook up the three pieces if I go with an amp to power the mains and also 2 subs.
Do I use my main pre-outs with a Y cables? Is it safe to split that signal 3 ways? One to the Main amp and another two to the subs?
Any and all advice is appreciated.
Thanks in advance!
