lets start with the lnb if its legacy chances are it will say d*** n*** on the front of it if its a dp it will stat that is your lnb is it 2 singles or is it one cassing with 2 eyes on it once you understand the operation of the receiver they become pretty easy to use the nice thing with you is you seem to have done some reading first let me know what lnb or lnbs you have and lets go from there as well as lnb list your dish settings and if theres anything wrong we can correct it and get you watching tv im just guessing but i think its a dp or ddp so you wont need a switch for 2 signals
