Domain user in local Administrators or not?

Can you give me some references to documentation of different user groups
on a Windows (2000/XP) machine? If my domain user does not belong to my
machine local Administrators, what ease-of-use harm and what security does
it really offer? The most widespread viruses (Sobig, Swen,...), does it
matter to them, whether I am in local Admins or not?

How about excluding my domain user from power users, too, being only a
regular user?
