Files from XP Pro to VISTA Ult - Office Pro 2003 to 2007

I'd like some advice please.

I'm currently on a DELL 8400 w/XP Pro SP2 and Office 2003 Pro; I am waiting
for a new DELL XPS 720 w/VISTA Ultimate and Office 2007.

1. Is there a complete list of files that I must transfer to the new
machine for Office to make sure that my contacts, emails and archived
folders are safe and what about my email rules?
2. I use a Data Base called Paradox Ver. 4.x and Ver 7.x will this still
work as I write code in PAL for systems we still use. 4.x (could be) is
considered a DOS program.
3. I use Netscape 4.7 to write HTML pages at times will this still work?
4. I have a 10,000 RPM C drive that I would like to utilize to keep the
machine's speed up and a 750 GB D drive. Is there a good way to optimize
the use of both drives with the OS and programs?
5. I've setup static IP addresses for scanners and printers anything special
here?
6. The current machine is on NORTON and the new machine is McAffe, any
considerations here?
7. Any general advice and things to watch out for on this upgrade would be
greatly appreciated. If this works for me then 7 others in my work group
will be doing the same thing

Needless to say I'm very excited about the new Microsoft Software and
machine.

I know I've asked a lot but this is very important to me and I ordered the
best that Microsoft has to offer because I want quality.

Thank you very much,

Paul
