Input needed on available speaker choices, please

I'm a newbie looking to upgrade my speakers. I basically have a bunch of hand me downs that I'm trying to spruce up without spending an arm and a leg.

To start, here's what I have (at least what I perceive to be relevant. Happy to supply more info if needed):
Integra DTR 6.5 receiver
Klipsch RC-10 centre
Paradigm PS-1000 subwoofer
Paradigm AMS300 V2 in wall for left and right surround
JBL S4 in wall for the front left and right (these I'm getting rid of for sure)
Toshiba DVD SD3900 player (connected to my Integra by optical out)

My plan is to upgrade my DVD player to an Oppo BDP-93 or 95. This player will pull triple duty as my blu-ray/ DVD and CD (rare SACD, DVD-A included) player.

This system is going to be used for home theatre and music.

I have a chance to land one of two (or both) of the following speakers:

1. Boston Acoustics VR950
2. DCM TimeFrame TF-400

I could get the BA OR the TF400 as the fronts and stay with a 5.1 system.

I could also get both and use the BA for the fronts, the TF400s for the left and right surrounds and relegate the Paradigm AMS300 to rear left and right surrounds and get the 7.1 system that my Integra supports.

Any suggestions or feedback would be appreciated. Like I said, I'm new to this, and am trying to figure things out.

Thanks in advance.
