[ubuntu-us-nm] Building own system and 64-bit

Ok. I have decided to build my own system rather than buy pre-built.
Why? I always wanted too.
Before asking the group thoughts on my configuration, I need some
explanation on 64-bit technology. It seams the more I read online, the
more questions I have!
I will be running a desktop with Ubuntu as a host and Windows XP as a
guest in VMware Workstation. As this will be a computer at my office, I
won't be using Ubuntu that often. My main computations will be in
Windows XP running ArcMap 9.2. The map files are stored on our server
running Windows Server 2003. I want to run Ubuntu as a host because I
am going to try to convince the office that switching to open source
will be fine. Plus, I need as much exposure to Linux as possible.
FYI: As I learn Grass GIS and R-spatial, I will be using these programs
more and more on Linux rather than using ArcMap 9.2.
Now the 64-bit questions.
1. Do I gain any advantage getting a 64-bit processor if Windows XP
(in a VM) runs on 32-bit, other than upgradability?
2. The processors that I am looking at say they support 64-bit.
But are they really 64-bit? For example, are the Intel Core 2
Quad, Core 2 Duo and the Dual Core all 64-bit? I do not think
3. If I get a 64-bit chip, can I run a 32-bit Ubuntu?
4. But, if I run 64-bit Ubuntu can I run software built for 32-bit?
Looking at the Grass website, there is a AMD64 version and an
I386. Does the AMD64 apply to Intel 64-bit too? And the I386
the 32-bit version?
5. What about VMware. If I run 64-bit Ubuntu, 64-bit Vmware, can I
run my 32-bit Windows XP? And, if I run the 64-bit VWmware, can
I transfer my existing VM running on a 32-bit Ubuntu to the
64-bit VMware Version?
6. If I go with a 64-bit processor and a 32-bit Ubuntu, will I be
able to utilize 8GB of RAM?
For your comments, reviews, etc, below is a list of my system
