Hi Tim:
Let me add my welcome.
It concerned me a bit reading in the same paragraph that you're getting Photoshop and asking if this is the right application.
While Photoshop without question is frequently the choice of professionals and serious amateurs, you can do an awful lot with Photoshop Elements 2 for a whole heck of a lot less money.
If you decided to start with Elements now and then make a transition to
PS down the road, skill / knowledge-wise what one learns with Elements translates nearly 100% to Photoshop.
RE:
PS tutorials
While not PS7 specific, this is one of the better tutorials I've found on the net for basic Photoshop skills. (Many of the lessons apply to Elements as well.) It is based on PS5, but conceptually, applies to any verson.

Regardless which software you decide to get, be prepared for a fairly lengthly learning curve.
PS or
PSE are nothing more than a box of digital tools... and a box of tools does not make a carpenter, plumber, electrician or digital restoration artist. It takes time and experience in order to learn to use the tools well. You'll be greatly disappointed if you think within a couple weeks after spending hundreds on Photoshop that you'll be good at using it.
I'm not you this to discourage you, but to give you realistic expectations. Although the learning curve is steep and long, to me the seemingly endless learning opportunities Photoshop affords is like getting ice cream everyday. I have enjoyed and continue to enjoy the journey.
Welcome again and hope to see you around the fourms.
