So you cover the entire surface of brass with toner except for the areas
where you want holes to penetrate (e.g. SMT pads)?  Then just let it float,
face-down in the FeCl?  I would think it's tricky to make sure the bottom
side is immersed and etches successfully while providing the top side from
completely eroding (unless you toner-transferred both sides, carefully
lining up?)

I wait ;-)

Yes.  2-3 mil seems to be best for the size parts I use.
