When you boot from your installation CD, it should give you the option of formatting and partitioning the drives before you begin.
I can't remember what the package options are, but you could try going for a minimal install (if that's an option). Once that is done, set up yum (there are many sets of instructions on how to do that on this site, and on fedorafaq.org, and on stanton finley's setup guide, and probably on mjmwired.net). The packages you'll probably want are
yum install firefox
yum install openoffice.org-writer
yum install thunderbird
yum install acroread
These will probably need other dependencies, so if it tells you it wants to install other packages too, don't worry! If you get stuck with yum, have a search around on these forums and on Google, like I said there are many guides about. If you need more advice, ask!
