You did an ok job for starting out. It's just been me and RandomPlayer and any extra help we can get is appreciated. One thing you should do for the formatting of new pages is include categories at the bottom of pages, I did it for the pages you already created. What is it that you have questions on for formatting things? I can try my best to answer whatever questions you have.
If you're not comfortable with formatting, simply adding information to pages would be great. We can always get to the formatting afterwards, and it's a lot easier and faster (for me) to edit a page rather than start a brand new one.
If you're more of the experimental type, you could always practice on your wall. I only know basic stuff myself, so I probably can't help.
