Assuming I got your questions right right:
1. If you have the preinstalled stock android and go through with the normal 4.3 update automatically offered by google, it won't affect your apps.
2. Rooting will only give you more "permissions" to change stuff on your phone. Some apps actually require the phone to be rooted to work properly. It should not affect your apps as well. Keep in mind that we are just talking about rooting. If you do this for later usage of another rom, installing that WILL affect your apps.
Hope I could help you.
