I highly recommend you become acquainted with the tools before you start doing tutorials, otherwise you will cause yourself some needless stress.
On the tools panel you will notice some of the boxes have black arrows pointing to the right at the bottom right hand corner. This means you can right click on that tool and select other tools of its type. If you hover over each of the icons, a little message pops up telling you want the tool is (sorta like what happens when you hover over images sometimes on a website)
I recommend you go through each of these tools and experiment with what each thing does. It is better to know what you are using beforehand.
Rotate a layer - use the “move tool” (1st one 2nd column) If you hover around the outside of the bounding box it creates (dotted lines with blocks you can drag to resize) you will see a curved line with arrows, this means rotate.
Paint bucket - It is in the same icon as the gradient tool (forget location, but it is in the second column, maybe 4th one down???).
yo dude, you need to go here http://photoshopgurus.info/beginner.shtml
that will get you acqauinted with the tools at least and from there you can actually follow tutorials, otherwise your going to be lost!
