Welcome Dawn!
First, I would suggest signing up for the e-zine. Shelleyrae wrote a great article in there about organizing your digital photos.
Second, by cropping or rotating, you won't decrease picture quality. The only way that would happen is if you increased the size or saved is as a .jpg over and over.
I suggest reading this thread

Also, try out the photoshop tutorials. There is a wealth of info there.
Lastly, ask away! We are hear to help you!
