Office 2003 to 2007 migration. USMT 2.6 or 3?

[#1]

Hi all
We're in the midst of a desktop refresh project and plan to migrate our 1500+ users from XPSP2/Office2003 to XPSP3/Office2007.  We read a Microsoft article that states that USMT3 does not migrate mapped network drives and network printers but USMT2.6.2 does so we used that instead.  However, during testing we discovered USMT2.6.2 does not migrate settings to Office 2007.  So it appears we must use USMT3 to migrate our users' Office 2003 settings to Office 2007. 
1. Is this correct?  If so, how can we also migrate our users' mapped network drives and network printers please?
2. We heard about a USMT3 gui wrapper from Dan Cunningham called Workstation Migration Assistant (WMA) http://dcunningham.net/2007/11/22/a-quick-look-at-workstation-migration-assistant/ that simplifies the process.  What are others' experience of using this, with particular reference to our migration scenario please?
Thanks
Scott

If you've wasted paid all that licence money, surely Microsoft will donate free of charge an integration expert?

[#3]

they wont be interested, upgrading from xpsp2 to XPsp3, should have done that over a year ago

I wish we could upgrade to Win7 but it's out of my hands unfortunately.
Anyone care to share their USMT knowledge to help our cause please?
Cheers

the jump from XP to Win 7 has some problems, cant you run a test machine on your network?.  Its a long time since I was on a big network, we even had a private cross atlantic link via Goonhilly.  I just have this Media PC running Win 7 the wife a netbook on XP SP3, a larger widescreen laptop on XP Sp3 and a netbook on linux, but not sharing anything

Win7 is a whole different ball game for another day.
USMT is our current headache...
