Search for 'Myspace Layout generators' , many of these sites have step by step instructions on how to 'pimp' your myspace
This one is a basic one, but there are 100's

Also, if you see something you like on another person's myspace, eg a slide show, often there will be a link attached to it somewhere going to the site that created the slide show - hope that makes sense!
Enjoy
