I dont know much about ghost 2003 but im pritty sure thats not what you want. You will want to buy the enterprise version of ghost. I beleave its upto 8 now, i have 7 personaly and it works fine. As for sysprep, if you dont run it you will not get a new SID in XP and you will have all kinds of issues on the network. That cheep program still exists in ghost enterprise 8 that changes the SID but i can tell you it wont do anything near what sysprep will do for you, sysprep basicly re-runs windows setup only it skips a bunch of the crap like detecting drivers and asks for the system name and if setup it will join a domain for you using that new system name and reboots the machine and your good to go.
