Well done old chap
I'd leave the other options alone for now
You can download "RomManager" from play (market) which is safer if you want to explore some of the other options, but really no need to worry. Now you are rooted you can use some of the better apps like "Better battery Stats", use different launchers to their full potential (Apex & Nova for example).... I'd recommend Voodoo Root Hider as well as you may find some instances where you don't want root (some banking apps, skygo...) and voodoo will temporarily hide root to allow those apps to work.
