Help with Forum Skin

[TRStealth]

Alright, I've installed the Category Spacing hack from here, but I need some help. I need to add some 'border' images around the seperate category tables. All I've been able to add was the strip color, but I also need to add something on the bottom of the table, and to the left and right, but I don't know which table holds the category table.

I also need to modify where the category strip is. I have an image that goes with the strip, but I have to place it manually because it's a seperate image. Where is this located?
