kudzu is a RH (only?) tool that is used for auto hardware detection and ( is supposed) to make your life easier with things related to that, such as editing fstab and so on. I am always eager to suggest dropping that once you've reached a level where you feel you no longer benefit from that (you like mounting and umounting your devices to know what's doing what).
Sendmail, well that ones pretty straight up
If you don't have a mailserver setup on your box, and completely use your ISP's servers, you don't need that.
httpd, this is Apache. If you aren't using it, or aren't running an http server, you can disable it..
