Well, a picture would be worth a thousand words here, so I'll try my best without one.
First, have you seen the sparkle traisl tutorials yet? I think I showed it to you when I first made it...

You can easily make a brush to suit your needs. This is one of the easiest effects brushes to make.
For the dust shape, I'd use something like an octagon, maybe with curved sides to make it a little spiky. You can use several brushes for this, one square, pentagonal, hexagonal, etc and just paint a few trails with each brush. Even tiny flowers or whatever will work.
For gold, you should probably make a style. Use a bright yellow color overly with a white outer glow. Put an orange/gold stroke around the layer like in step 12. Remember, to make something look like light you need a super bright center and the color glow around it.
Add some bevel>texture to the style and choose something grainy to give a dust look. Have fun!
Remember to post your results here so we can see how you did!
