You mentioned that you are interested in books.
Personally, I've done very well with the O'Reilly series. I have a few of them, I think probably for your purposes, you might want to look at "Web Database Applications with PHP & MySQL." This has a good overview and examples of all the PHP and MySQL that you would probably use for what you're describing. Of course, there are a lot of other good books, I'm sure.
You should be able to get the book on amazon.com .
