Yes. It is a slight benefit if your multiple network cards are more
or less busy (i.e. you would get an interrupt from it a short time later).
A less overall interrupt count of course helps performance, under any OS.

No. The interrupt routing can not realy be influenced by the software, so you
have to be able to deal with all shared/unshared scenarios. PCI drivers can
not make assumptions like "this interrupt is mine only" and optimize for
that.
