Installing Xcode Leopard

I searched the forums for help topics on this, but couldn't find anything that directly helped me. could someone help me out here. I have the 2008 Macbook pro and all my installation discs (1 &2) and the "CPU drop in DVD". which disc contains Xcode, and do i need to reboot to install it, with the disc in?

I remember trying to do this when i first bought my mac but had severe problems, so i just gave up, but since i recently signed up to macrumors and now need to program a software assignment, its a neccessity. Is it worth using the version on the disc, as there may be a much newer version out. my googling turned no good information up on the various versions and which one i might have. However I am currently in a library with slow internet, I pretty much don't have the option to install download a newer version.

thanks in advance for any help you can lend.

 

ah, i have found out why i had problems. i assumed OSX upgrade to leopard disc contained only the leopard OSX stuff, but it also contains the version of Xcode for leopard. that was obvious. i'll probs think about these thing before posting in the future aha. thanks
