There are several photoshop specific forums. There are many tutorials avaliable, just Google 'Photoshop Tutorial'. There are several books avaliable.
Photoshop is a large, professional program, I know my way around it...but I don't understand all about it. Start with the basics and go on from there, rather than trying to understand it all.
Depending on how much background you have, Photoshop Classroom in a Book is a great teaching tool. It takes some time since it walkes you though projects step by step but you'll end up with a great understanding of the program and it's possibilities.
im new to photography as well, trying it out as a hobby. i will try the suggestions made here. hope dis works out. fingers crossed.
thanks all.
