1. Warranty void: 1 -> You void ur warranty when u rooted ur phone in android 4.3. You dont have to worry about the other words
2. You have to do the process of root 2 times sometimes. Try it and tell me how it works

Maybe ur phone is rooted but the icon doesn't appears. This happened to me too:

1. Install this app and verify u are rooted: HERE
2.Only you have to do a backup of your Internal memory and do factory reset (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything). It will reboot and u will see the icon of SuperSU again

1. You can't come back. (You can try but u will have millions of problems -> no wifi, no network signal, random reboots, overheating... without solutions)
2. About Multiroom -> Ask in the correct thread
