Windows reinstall will destroy your LILO/GRUB conf. I mean when you'll reinstall windows you won't have the choice to boot Linux. You're going to have to 'repair' the installation with SuSE CD1 bootable CD and correct the loader.
If you're going to freshly install WindowsXP and SuSE Linux you can just install Windows on the first disk and format disk2 with FAT or even NTFS. Then when you're going to install SuSE next to your Windows installation and SuSE will format it the way it's supposed to be but still be careful when repartitioning the hard drives. Have a look in there and choose to use the whole disk2 for SuSE (hda5 and/or hda6 and/or hda7 must be untouched, that's where Winodws are on most systems). Even if you won't, SuSE will just repartition one of your windows partitions and install it there.
I never had any problems with loss of data when installing SuSE as a second OS because I used E:\ for Linux that was blank. Now it's only SuSE on my system. =)
