Anyone know places to sell your stuff for cash?

I'm getting rid of some of my stuff and I could use some suggestions. I'm selling my books and movies to Hastings (if you have other suggestions, please let me know), and I need somewhere to sell my 4GB iPod nano (3rd Generation), my skateboard, Play Station 2 games and if anyone knows a shelter or somewhere I can donate some stuffed animals to (I live in Albuquerque, New Mexico), I'd appreciate that. Thanks! :)
