Photoshop :: Trying To Achieve Leather And Mist/moonbeam Effects

I want to design a template for my band's myspace, however the problem is with most artists, what I have envisioned hasn't exactly been going as planned when I try to achieve it in photoshop. What I had imagined is a template that had mist, fog, leather and moonbeams,

The first effect I am looking to do looks like this:

I had wanted to have leather as the background, as in not too detailed but shiny like this picture. However I have no idea where to start to make leather that looks this quality.

The second effect here is a mist, ghost like fog:

I pretty much am looking to do this effect scattered for the template, yet I have tried and have no where to start or accomplish this.

The last effect would be moonbeams:

All I really want is to have moonbeams that are similiar to this, no idea really what to do :/

Anyways I realize I am asking for a lot here, but I am in no ways advanced with Photoshop,
