Welcome Jess.
If you are planning on moving into a larger place and have been lusting after that combination and can afford it, then you have our blessing to go for it
! And why don't you upgrade to a 600 while you're at it?
The 500 (and I'm sure even the 350) will test the sound isolation of your building. In my house, no one can escape the frightening thunder of the 600. The choppers from Black Hawk Down made my jeans flap in my 4,000 cubic foot room.
In a place that small, you could go M3s (which have been getting rave reviews) and forego the centre channel for now. This would give you some additional money for the 600. When you move into your new place, you could use the M3s in another room (or go through Axiom's trade-up program) and buy M80s for your main room.
The 805 will have no problem at all powering M80s and the VP150.
You will end up enjoying whatever you buy from Axiom.
