Pretty important.

Your department doesn't have a PCB layout class? Some good discussion of
layout for conventional amplifier design can be found in Doug Self's series
of articles on amp design in Wireless World.

Your issues are a little different since your goal is to keep trash from
leaking into the output and keep the output from coupling into the modulator.
There is an Intel application note on RFI issues which you might want to look
at, which discusses digital layout and design.
