Haven't practically done this before. But here are some thoughts:
1) Have you installed SharePoint 2007 64-bit on your Win2003 R2 x64? Your MOSS 2007 should be having SP3 to support Windows 2008 R2.
2) From OS level, verify your upgrade paths -

3) As you will also be going for SharePoint 2010 later, I would prefer to go with clean installs in such scenario with backup/restore, so that you will have less headaches later.
Will be happy to hear which path you have taken and how did it go :)
Thanks & Regards,
