Request for a "How2" for changing colours in Photoshop?

[Craig1985]

After seeing so many people asking things to be changed in photoshop could someone post up some how2s for simple edits such as change or colour and wheels?

I have photoshop on my works laptop but aint got a clue on how to use it?
