I'm wokring on assembling my PPA now and I've got a quick question about the resistors:

In the spec it says to omit R3 on the ground channel (I'm more or less building this with no changes from the spec). I assume from loking at the design, it needs to be jumpered. Is this correct, or am I confused?

No, it means to leave it out, in order to set the gain to 1.

Yes, the ground channel runs at unity gain, leave it out.
