Well its installing the latest version it finds in the active repositories (sorry, just felt like stating the obvious). I'm not sure why it gave you the 64bit stuff though. Goofy versioning? You can specify the version in the package name like this (taken from the yum manpage):
Specifying package names
A package can be referred to for install,update,list,remove etc
with any of the following:
In short try this command:
yum install kernel-devel-2.6.11-1.1369_FC4
If you want to have an even easier time of things you could install the yumex GUI interface. However, the command line is much faster and yumex seems rather slow at times. I only use yumex for browsing the repositories most of the time.
