I have Comcast and I'm ordering the HD box, but I was wondering why it looks better with HDMI. Since coaxial is the original source coming into the house, how does HDMI improve on that original source?
My guess is the HD box does some uncompression and decoding of signals and then sends it to the HDMI cable.

It doesn't. If your tv has a built in QAM tuner, compare your local channels from the wall and then from the box. The direct line using the built in digital tuner will always look better.

You are correct.
The coax signal out of the set-top (not the wall) is standard-def to be used by old SD TVs.
Only component or HDMI can pass HD signals. And yes, the video signal over HDMI is uncompressed.
However, if you connect the wall coax to an HDTV with a digital tuner, you can get the HD signal as well.
