Much of this depends on how much work you're willing to put in. A list of the items will help people spot things they are interested in. If not a list, then spread the stuff out on the floor and take a picture.

Toys you could go to a reseller like http://brianstoys.com/ A main hub for SW toys buying and selling is: http://rebelscum.com/

As for magazines and comic, there are fan scanners who would be interested in certain titles. Otherwise ebay is a place to sell blocks of stuff. Your local comic book store might buy a chunk.
