Hooking up Question

I wanted your input on how I can hook up the home theater components


1. I have a HDTV with HDMI input & 3 component input (Pannasonic 47X54)

2. I have HD cable box (Comcast cable)

3. HTPC (With FX5200 video card & WinTV 250 MCE PVR)

4. Receiver (1 optical & 2 coaxial inputs)


How can i connect these components with least connections?


I want to route the output of HD cable box through HTPC (Is it possible to route HD signals with the present Hauppauge Card?)


Then I want to connect HTPC out to the TV (The HTPC has DVI out and my HDTV has HDMI?)


Any help is appreciated as I also need to buy necessary cables.


Thanks
