I putting together AV wiring diagrams for my electrician to pull wires next week. I know what I need for an HD Tivo or similar box but I have no idea what's required for satellite anymore.

For you Dish/D* users:
1) How many coax runs should go to the AV rack? I see at least 2 for SAT and 1 for OTA. Is that still valid?
2) Do Sat boxes have HDMI audio or do I need to account for a digital audio run?

I normally use structured wire which has 2x RG6 and 2x CAT5. If I have 2 runs of structured and 2 extra runs of CAT5 I think I'm covered. That gives me extra CAT5 to use wired IR, network, or use baluns for other uses. I could use the 4th coax as a digital coax. Sound right?
