I suggest that you take a look at Scott Kelby's book "The Photoshop CS3 Book for Digital Photographers. He has a very unique writing style that is exciting and informative without being dry.http://www.kelbytraining.com/?page=product&id=58.
You also might look into joining "NAPP", National Association of Photoshop Professionals. Among other things you get a discount on his and other books on Photoshop, Lightroom etc., also free 3 day shipping from BH. NAPP also holds one day seminars on Photoshop, Lightroom etc..
I have found that the web is a great source of tutorials for PS,bare in mind that PS7 or later tutorials are very relevant even though you have CS3. As you are retired you can do as I did and try two, forty minute sessions each day,EVERY day.As you are still a young fellow you should have no trouble mastering basic photoshop.I started on PS7 seven years ago at the age of seventy.I now teach PS basics to several groups of people,Good luck,and remember that the "retouching" forum on this site is a great source of help.Frank Perry..
I like Scott Kelby's "7-Point System for Photoshop CS3".
It has 21 step by step lessons that build on each lesson. I've been happy with the things I can now do on my own photos, even though I have not completed all the lessons in the book..

Second the Kelby 7 points book. It's really focused (no pun intended) on CS3 for digital photographers and doesn't get bogged down in a lot of stuff you'll never use or won't use 'til you're much more advanced. It teaches a good, basic photo workflow..
I belong to NAPP and the book is about $1.00 cheaper than Amazon. Look forward to learning...
Can you please tell me the web site for the PS 40 minute lessons? Thanks..
I was not referring to any particular 40 minute lessons,just indicating that (for me) forty minutes at a time was enough for my attention span..
If you do a search on the web using "free photoshop tutorials" you will get several thousand hits,it is then just a matter of sorting to get those that suit you. If you need any help to find specific tutorials ,come back here and I am sure one of us can help..
