heh, my mom wouldn't let me plug in the Apple IIc portable into the television set, just so i could get games & apple logo/basic to work in colour. that was the early 90's i think.
i suppose, things haven't really changed that much
the hardest/dangerous problem with bootcamp is repartitioning, not the windows install. especially on a laptop.
have you considered using crossover instead of wine/cedega or parallels/vmware ? cedega would be easier, but the dx8/dx9 issues might be insurmountable, i suppose.
you really just dump the 5gb folder into the cedega folder, edit the cedega files to point to gw.exe, and run gw.exe to check and update gw.dat, which inserts the registry entries for guild wars, and downloads updates. there's guides for setting up other apps via cedega, so it couldn't be too harsh.
if youre still fixed on bootcamp, download superduper + get a cheap ~250gb usb hdd from the store (ideally one that's at least 2x larger than your macbook hdd, doesnt have to be a portable drive or have firewire either - firewire would be faster), backup the macbook hdd to the external and boot from the external drive, see if that works first. it should take a few hours so you can read over the bootcamp manuals, how to switch drives for booting up, etc.
after you've booted from the backup drive to test it works, then do your bootcamp prep. you can then later on leave the external as is, or occasionally you can do redo the entire drive backups to the external (superduper only copies over changed files ), and/or partition the rest of the external hdd to use as a time machine backup partition.
if the procedure goes screwy, you've got a solid, if slow, backup, and can restore everything back without any drama.
