Welcome to the forums, PaulK!
We were all once noobs so don't worry about it. We're glad to have you here.
What exactly are you looking to customize? Are you looking for a different "look"? You can change the launcher from stock TouchWiz to GoLauncher or ADW (among a million others) which will allow you to do a whole lot more. They're both free in the Play Store.
In terms of dialing a "code", I'm not exactly sure what you mean (and this is likely carrier dependent of AT&T which I'm not familiar with). I recall a couple years ago changing a setting that way to slightly improve my call quality. It is something that CAN bork your phone.
If and when you're ready to root, check out the All Things Root guide for the Skyrocket and ask ANY and ALL questions you have. We're here to help.
