That makes your decision making a lot easier, you cannot extended the
Samba schema with the exchange schema (as far as I am aware) and even if
you could, you would be lumbered with it for ever.

I would start with a new domain. Your computers will need to leave the
old domain and then join the new one, this will probably have to be done
manually (just a question here, how does a user use 2.5 computers at
once ?). I think you will have to recreate the GPOs in the new domain,
they are stored in SYSVOL and AD.

No, more like a million ;-)
