The daisy chain can be up to 9 guns, so yes it can continue.
A T20 or 32 on the PBG2 can always take power from the PBG, irrespective of
how it is connected to the camera.
If you go for tripod mounted lighting, you either need to guarantee where
the subject will be (eg leave bird - food to attract it) or use diffusers
and go for wide-area lighting.
I'll leave the F number debate for others, but if it is really important to
you for flash, you would need T stop equivalences for each of your lenses.
I've never seen that published for Zuikos (but I admit to never having
looked for it).
