Well here is an update:
I received my Linksys router yesterday and hooked it up. I had to make some configuration changes since I already had a router, and I just wanted to use the Linksys for the phone, so I wanted the Linksys to work off of the Netgear router. After that was configured, things worked beautifully. I am just waiting for MCI to port the number over.
Right now I have a temporary phone hooked up to Vonage, and my primary phone hooked up the MCI... Once the number porting is complete, I'll go ahead and make the switch, since I think it is pointless to give out the virtual number (it will only be used for a few more days).
It is just so cool not having a phone plugged into a wall jack and when you pick up the phone - there's a dial-tone. So cool!
