Hello Guys,
Using 3.0.4 VB and host is vista and guest is winxp os. Do I only install windows guest additions once then dismount it so that the guest os can use the cd-rom for other media?

Yes.

Of course. Why do you think it would need the GA ISO loaded all the time? If that were the case, VB wouldn't be used that much .

Thanks Guys! I really appreciate the info. I want to do this accurately and efficiently.
