No worries mate ... I am probably a bigger newbie than you are ... I just bug ppl a lot until someone gives me the answer
Mandrake has something called urpmi ... its a command line tool that lets mandrake automatically go out ... search for rpm you want ... find its dependancies ... download and finally install.
rpmdrake is a front end gui (the add / replace software in the mandrake control center). You just have to add more sources ... one good place to do this from is http://plf.zarb.org/
which actually does lossa good things for you.
Once you have it installed would you mind telling me how the freaking ed2k links work?
