It sounds like you have the major areas covered.  Have you thought about
installing vents in the walls around the bench work areas (coverslipping,
manual staining, etc?)
We did this during a not so recent renovation and works very well.  No wall to
wall hoods, but the fumes are directed "away" from the worker and everyone is
pleased until someone turns the switch off.  These wall vents are all tied into
a single ventilator (you dictate the size) located on the roof.  Works well for
us.
Good luck,
