I've rooted all my phones in the past, is there really a reason to root this on its already got plenty of space and it's fast, how good are the rooting programs out there anyway will they screw up my phone?

The two main reasons I rooted were for TiBu and AdAway. You also occasionally get access to specialized settings in apps. For instance Widget Locker has root options that help hide the notification bar etc...

Which way did u root your phone, Odin or gs3 debugfs root r2? And did it screw up your camera

I used debug method. Easy as pie. Camera is fine. And you can use Odin to return to stock for warranty purposes.
