Yes. Every server also needs two IPs ond VIP and one IP and every Server needs 
to be registered in the Windows domain.
Just like the "active/active" Microsoft Cluster Services work.

No. Basically every server serves exactly its shares exclusively. HA-services 
take over the availability. But the active/active granularity is the share. 
If you would like to have real loadblancing you would need a samba which is 
capable of that (I also heard samba4 will solve that issue).

That is not possible.
Sorry for the missunderstanding
