Profile question

I recently started using vbulletin, and so far I really like the way it works. After trying out a few hacks and getting a feel for the way the board is structured, I am aiming to create a custom profile hack so users can add additional information to their profile. The message board is going to be used for a RPG Gaming site, and I want to give the users the ability to put their game character information in their profile. Basically the type of information I am wanting to store is as follows:

A) Character Name
---With support for up to 8 characters and for each character the following info:
1) Level
2) Class
3) Picture/Image
4) Other Info

Since I'm in the early(planning:)) stages I don't have a specific technical question yet, but am mainly looking to see if anyone can point me to a similar hack if it's already been done, or point me to any other resources that can help me. I did do a search and didn't find anything that looked like it would help me, but might have missed something too.

I have a little programming experience, but I am new to PHP/mySQL and vbulletin so a similar example or two to study should help me to get going.

Thanks,
Ben Murray
