For sure, I am not very experienced in Linux, too. But I installed the Kernel sources via the Redhat paket installer tool.
I use a german distribution, the program is named "Hinzufügen/Entfernen von Applikationen" here. I thinit its english pendant is called add/remove applications or something like this.
This tool fails with uninstalling, but I never had problems, installing some packages...
