Need help with setting up Xbox to stream movies

Gents,
I have an Xbox 360 and want to be able to use it to watch movies on Comcast, Netflix, Amazon, etc. What do I need to make this happen? The house is set up for wireless.
Thanks.

Comcast: ???
If you already have a wired connection, a wireless would not help in this regard. It doesn't appear that they have actually implemented it yet, just announced that they will be in the future.
