Hey melo!
Finding tutorials for Photoshop is really easy, by just typing it into google, but I have found you a couple of links that will help you create different things in Photoshop, plus learn your way around the interface of Photoshop.
Photoshop Essentials -- I've linked directly to where you'll be able to learn the interface; brushes, making custom swatches, working with layers (which is really important), etc.
Adobe Tutorialz -- Here is a site with just a bunch of little tutorials that you can learn. If you click on Adobe Photoshop on the menu to the left, it'll show some more tutorials.
Also, if you want to look for some more, when you're typing in Photoshop Tutorials, make sure you add in the version of you have, so "Photoshop X Tutorials" and where X is, just add in whether its CS, CS2, or CS3, or CS4, etc.
Good luck to you and if you have any further questions or need help searching for some more, let me know!
