In my opinion, you could safely disable all of them except for 1,4,9,11,12,15,19,20,23, and there shouldn't be any problem. It depends, however, of the programs you usually use and what they depend on.

You don't need 15. Network starts the nm-applet. You can always enable it later. Just run nm-applet from a commandline. –  user85164 May 5 '13 at 15:08
