For your method..
a. Boot into XP
Remove the Vista boot loader with VistaBootPro or EasyBCD installed in XP.
Restart and test, if it doesn't boot, restart with XP Cd and run a repair XP install to fix the mbr or if you've XPSp2 use the Recovery console and the fixmbr command

b. Use XP's DiskManagment to delete the D partition leaving unallocated space
c. Vista will properly format the drive during the install to the unallocated space(select Custom install in Vista and ensure you choose unallocated space)
d. Yes.
e. Rerun VistaBoot Pro or EasyBCD and backup the bootloader files, choose a default o/s to boot, set timeout for dual boot menu, and names of each o/s
