Plea for Help

Alright all you bloggy readers out there...I would really like to change things up and the backgrounds from blogger are just not cutting it anymore. I don't want to change where my blog lives, just give it a makeover.

I am apparently more technologically challenged than I realized...I'd like to use some things from ShabbyBlogs.com but cannot figure out how to apply the changes with the new template designer on blogger...anyone out there know what I'm talking about and how to make the changes I want?

HELP!!!!
