I don't know the answer to (1) and (2), but I use Amersham's Hybond-N
membrane for Southerns dot blots and colony/phage lifts, and I've
mostly used ammonium acetate as my neutralize and transfer solution. 
I've not noticed a difference compared to Tris-HCl neutralize and SSC
or SSPE transfer buffer.
