Welcome to
RTP, driley. :-)
You have picked a doozy to start with. I'm not a retoucher, but can see that this photo has a terrible light leak problem. To correct this you'd need to do some channel mixing and masking and, not to be discouraging, but for a beginner it's a daunting task.
I want to encourage you to jump into Photoshop (or what ever editing program you are using) and I would hate to see you get discouraged. Also, any advise that folks might give you here will be really confusing if you don't know the basic terminology they are going to throw out to you.
My recommendation would be to start with something a little easier. Also pick up Katrin Eisman's book "Restoration and Retouching". If you can find a copy with the sample files on CD fine, if not she gives the web site where you can download them.
Understand this is coming from a 66 year old granny former school teacher. :-)
