Any potential problems I'm overlooking if I clean guns on the same bench I reload on???

Obviously, you'll want to avoid contaminating your primers and other components with solvent/oils. Remember, if you use a brush, they have a tendency to spray a fine mist of oil/solvent as they clear the muzzle/chamber.

If you have a press on the bench take care not to clout your rifle on it. The press/die is unmarked, the rifle not!

Antlers,
I clean my rifles in my loading room. I suggest that you don't use aerosol of any type in there. If you do use aerosols, do it in the carage or outside. Good luck.
