How do I remove or change the footer section of BlogMU theme?

Hello there,

I would like to remove the white colorful footer at the bottom of the theme or change the text and links as well as the bg colour. I looked in footer.php and found the area but want to double check before I butcher the theme. Thanks SO very much!

Also,

Do you know of some great step by step tutorials programs to learn php and css better so that I can eventually build my own themes? Greatly appreciated, love you guys to bits!!

All the best,

Elyakim Samuel
