Switching from Directv to Dish Network HD, wiring questions

[3dmdlr]

Greeting everyone. I am new to the group. I did a general search but I really don't even know how to ask my question. Currently I have a Directv Setup:
Living room = HDDVR with 2x coaxial lines in 1x OTA coaxial line in
Master = tuner 1x coaxial in
Bedroom1 = tuner 1x coaxial in
Bedroom2 = none

Going to Dish Network, I am getting the 622/722 HD/DVR in the living room/1 bedroom.
How many lines IN do I need for the HD/DVR, and then how many lines OUT do i need to support an additional SD TV from that tuner?

The other 2 bedrooms are getting the HD Solo 211. Do they require only 1 coaxial in?
The mutliswitch I am currently using with my DIRECTV, will that be used for Dish Network as well?
Or is it out of the equation all together?
Are there as many cables required for the Dish Network disk as there are for the DIRECTV dish?
Thanks in advance!

Also, I plan to run cat5 for network connections as well. Does the 622/722 and 211's utilize a cat5 connection? Thanks again

You need 1 cable from the dish to each receiver. You need no switch since dish builds theirs in their LNBF.
