Suggestions on a Fresh Start with OS 10.3 X-server G5

The company I work for has recently purchased an X-Serve G5, and I am in the process of reformatting it and installing the 2 hard drives in Raid-1 (Mirrored). Also, we have about 15 users who log into a Windows NT4 PDC computer, and I need to either migrate them, migrate their application settings, or start completely clean. Personally, I'd like to wipe it all, but they for some reason want their profiles. We tried migration before (without the mirrored drives) and had troubles with Samba and Win2k. Mostly read-write and permissions errors. Anyways, if people have suggestions, please let me know!
