First of all, thank all of you for your valuable (and quick!) answers. @Massimo DP: Just for curiosity, any expected date for the release of the new editions?
@Anthony: great suggestions! I spent all the day with http://www.w3schools.com/, http://www.webmonkey.com/tutorials/, and that was exactly what I needed! Obviously it is still a long way to go, but that material is great! @chawk: yes, you centered the point! thank you for the detailed answer. I started with the material suggested by Antony and will now explore the books you suggested. Hopefully I'll get there, and I wish you the best for your application! :) Thanks everyone again!
