I'd call Dish and pay the $15 to get set up.
But as for DIY, you need the following:
1. 500+ Dish Kit, including mast and struts for stability.
2. Dish Pro Plus 33, or 44 Switch.
-The reason for not recommending a Dish Pro 34 switch is because if you have a dual tuner you'll need 2 lines going to the receiver.
-If you wind up diplexing your setup for TV2 you should run a dedicated line for the power inserter. Do install power inserter outside!
-44 switch is for HD setups that use the 129 sat or a wing dish.
-The 33 switch is for SD setups.
3. RG6 coax and
compression fittings for weatherproofing the connections outside. Don't forget to torque them down.
Here is a diagram for a diplexing setup with a 44 switch. a 33 is basically the same.
