Photoshop help and new Jewelry

WOW sorry thats a bad picture, but I love this bracelet, more like it are in the Etsy shop to the right!

This is my new little invention, its a cluster with a lobster clasp at the top, you can clip it to your favorite chain, Then buy other interchangeable clusters, and save lots of money.

I just got Photoshop for mothers day, I still haven't figured it out(^obviously^). But when I am driving I am constantly looking around me for places to take cook pictures, I have taken a lot of them, but...Now I need to learn how to use Adobe photoshop E8. Do you have a favorite Photoshop help website or a favorite tool that I should try??? pleeeeeeeeeeeeeeeeeease I am overwhelmed.
