I'm home sick and have nothing better to do, so I'll type up a quick tut on backgrounds.
No detail here, sorry n00b's.
Hit D, sets colours to default (black/white), render clouds until you get some good ones. Brush over that layer with a grunge brush in black, next layer a different grunge brush in white. In the next layer take a abstract brush of some kind and brush white if you want a lighter background, and black if you want a darker background. On top of that do more brushing like the first two layers, switchign colours everytime. You can change the blending style or opacity to the brushing layers for a softer/harder effect. I prefer to change opacity so you don't lose some of the brush detail so randomly. Over top of all that now, use another render-clouds and set it to overlay/soft light/whatever you want. Experimenting is the key here. Now if you've got a plain b&w background that might look kind of boring. On top of all that stuff make a new hue adjustment layer. Set this to the colour you want at about 40 opacity (you can vary of course). On top of this a colour balance layer makes the effect soooo much better. Let's say you have an orange background. On midtones you would slide the bars towards red and yellow (leave green/magenta alone), slide shadows a little over to blue and cyan, maybe a bit of magenta to keep the reddish ornage tones, and finally slide highlights to yellow and red a little moreso than what you did for midtones. Generally you shouldn't move the sliders past 30, but if it gets the effect you want do whatever you want. Now you have a good background. On top of this you can also use a brightness/contrast adjustment layer (3 adjustment layers!!!) and fiddle with contrast to get a softer/harder effect.
There are a lot of variations on this as well. You can use difference cloud filters on the cloud layers, you can have multiple hue layers and fade them into each other using gradients/brushing on the layer mask that automatically comes up, and it goes on.
And nice BG fender.

But like has been said the text is bleah.
