SuSE Update and General Updates?

I've seen a number of posts about SuSE Update and I'm a little confused as to what type of programs etc. will update while I have SuSE 8. Can anyone provide some guidance on the following. WIll it only update security patches to a select number of programs? Will the KDE 3.01 be available fro update using the SuSE Update (control center)? Will SuSE provide updates to all programs that came on the SUSE CDs (such as mozilla 1 when it comes out)?
