The bootcamp install will work fine if you print out the install instructions and go through them step by step. Make sure you have a time machine backup made on an external hard drive just in case something goes wrong. I have had to completely wipe my drive once and re-install leopard to get bootcamp to be able to partition my disk successfully. When you are going through the install of xp, like was said above, make sure you are selecting the right drive to install windows on, if you select the wrong one, you will erase osx. You don't need the bootcamp drivers for the computer to be able to run, you just have to have them to get all of the features out of your computer like sound, and if you have a macbook, the multi-touch trackpad and such. If you have any problems just look through the "windows on the mac" forum and if it is not answered, create a new thread and ask.
NOTE: The bootcamp installation process makes windows the default operating system, so if you just let the computer boot up, it will boot into windows, this helps with the installation since it has to reboot so many times. If you want to get back into osx, restart your computer and after the chime noise, hold down the alt/option key and then select your osx partition. If you want to make osx your default OS so you don't have to hold the option key to get to it, in osx go to system preferences --> startup disk. and click your osx disk
