I am in 6, but I've done it in 5.5 and the methods are close. I just used the emboss tool in the layer effects. It looks like you have a drop shadow too, that does'nt work all that well. I put my type on a layer, and used the bevel and emboss tool. In 5.5, I think it is under layer effects. Direction for it is down, you might need to tweak it alittle until you get what you need.Good luck! Green Lantern was one of the coolest!
