A very, very good book for this type of thing is written by Katrin Eismann, Photoshop Restoration and Retouching. It is really great and goes into a lot of detail.
A wonderful website for this type of thing is:
http://www.retouchpro.com/forums/
If you check out the site, you'll see challenges, people doing Katrina restoration...you can post your picture and people will play with it and tell you how they did it. It is a lot of fun. I really enjoy looking at the posts on this site. You might want to post your photo there if you still need suggestions. I'd give the book a whirl also, if you think you'll be doing a lot of that kind of thing. Good luck.
