[Q] Which STOCK apk can be remove? topic

Hi all,

I just rooted my s3 mini and would like to use STOCK rom. I want to stop those S Planner and etc software that run at startup and so as I know, the apk is located at system/App right?
Anyone done that before? Can someone give me a list of those stock apk that can be remove/rename?
Appreciate your help guys.

Thanks
