Boot Camp, Mapping Network Drives, having them work in my XP VM...

This is a general plea for advice... I'm not sure of the best way to set this up... here is my setup and what I want to be able to do.

On my Mac Pro, I'm using Parallels with an XP boot camp partition as my only VM. Half of the time, I want to be able to be able to boot cleanly into XP to run my 3ds Max. While booted into XP, I have set up several mapped network drives, pointing to shared Folders on External NAS and USB drives. So I've got a "P" drive for a projects folder, an "S" drive for a storage folder, "M" for media, etc. I really like this setup because I have several XP computers on my network, and they are all configured the same way so I always know were to find stuff no matter what computer I'm on.

Then I bought a Mac...

So now, I want to boot into OS X half of the time. When I do, I want to be able to start Parallels and load my VM that is based on my boot camp partition. I do want to see my XP partition from finder, and I do want to see my OS X drives from XP, and this seems to work fine. But I also want my mapped drives to show up in the VM exactly as I set them up previously. In windows, the mapped drives are still "mapped" as I set them up, but they show as "disconnected network drives". As it is, they show up as X,Y and Z Mapped drives, but they are just the roots of all the shared drives. . So I can access everything, its just not being displayed to me like I want it to be.

Also, one of these drives is hooked up directly to my router (netgear WNDR3700) via a USB cable... and in the VM machine, that drive doesn't show up at all, although it does from the Mac side.

I have a feeling I'm missing something basic, but I cant see the forest for the trees. Any help would be appreciated.
