I've always wanted to have a go at custom roms but never got round to it. Might try that.
Yeah it'll definitely help. Just back up to Google or Samsung in the Backup & Reset menu and you won't lose WiFi passwords, etc.

First off though try a cache partition wipe. It's like a mini reset without resetting anything on the phone but can clear glitches built up over time.

Worth doing and giving a couple of days before doing a full reset.
