Keep the FC up until I don't feel the slime right?
Yes.

I still don't understand the muriatic acid instructions
Read the muriatic acid page that is linked in my signature. You only need to add acid to (a) lower pH, (b) lower alkalinity, or (c) adjust for borax additions. If your pH & alk is OK, and you don't want to add borax, you don't need acid.


Am I trying to lower the CYA at all?
It's up to you. You have two choices:
-1. You lower your CYA, and operate with 'normal' chlorine levels.
-2. You don't lower your CYA, and instead operate with Best Guess adjusted levels.

I'd recommend #2, but you can't really do that till you have the K2006
