Cisco VG200 w/ 2VIC 2FX with a Voice Gateway 200 and no PBX just Call Manager Express on 2621XM.?

I know this sounds kind of boring and all not having a PBX (down the road) but this is for simple home use. I have a Cisco 2621XM w/ Call Manager Express, a Voice Gateway 200 w a 2 VIC 2FX card, and a 7906G VOIP IP Phone. All I (boringly) want to do is plug in a phone line into the VG200, run it through the 2621 w/ Call Manager Express, and ring ring. Sounds simple, over complicated for a basic phone line but there is a bit more to it down the road. Is this relatively easy to do? Also, how is licensing handled? Always the fun buster... Thanks!
