Default Pending updates? Disregard?

Hi, i have never done updating the phone through update center. I have d802C and i know there are more updates pending in the update center.

my question is when kitkat comes will it overwrite the latest software update or do i need to install everything up to kitkat? can't i just ignore them all and install kitkat?
