Well I guess my question is, do I run it so that the bubbling water is at
the bottom of the collection cup tube and it will foam up to the top later?
Or do I run the water level towards the top of the tube?

Definitely at the bottom or lower. I currently run mine about 6" below
the lip to the collection cup, and I had to use an anti-foaming agent to
get it to condense.

Start off with the water level low. If you don't get any skimmate, you
can always raise it later.
