Edit Settings customization

I like the ability to edit all the settings in the front end, but most of the people signing up for my site are more than likely get confused if the edit settings is asking them what help site they want and such. I was wondering how to edit those settings so it can just show "show online status", "show email", and "signature" options.

Side note, I like how this site has the my profile page set up, any chance someone could tell me where to edit the layout of the my profile page?

Thanks :]
