Ah, you run a group?? lol That's kool.
Don't worry about it, I haven't used PS in so many months! I should really start using it again lol.
Ok, (I use CS4 now, I made this with CS3 but I hope its still all the same XD) so, to add bevel you right click on the picture/layer (for example, the shape you want to use, in this tut it was the the layer with the [black] pattern on it) then you select 'blending options...' And the 5th box should say Bevel and Emboss.
For hight and scaling, go to Edit>transform>scale. (make sure you are on the layer you want to use it on, and after you have made your adjustments, there should be like a tick symbol at the top of the screen, click that, or the symbol if your not happy and do it again).
I hope thats what you asked for lol
Any part in particular you're stuck on in the tut? Just give me what step, i'll try my best to help XD
I did really think I had covered it all, guess not lol.
