yeah EMG's are generic of the metal category. good but not great. If you're going to do it up Seymour Duncan style, I'd suggest the Dimebucker, the Invader, the Pearly Gates, or the SD's. Either of them are good metal pickups. You should really go to a guitar shop, though, and try each of them out to determine what sound you want out of those. Most shops will carry a good selection of Seymour Duncans if they are an ok shop. I used to use a Bridge Dimebucker before my guitar got stolen.
It's all a matter of preference really. Names don't mean a thing, so just look for whatever pickup looks ok for the guitar and sounds like you want it to. It's the amp that really gives 95% of the sound anyway, so pickups wouldn't be the first of my worries if I was in your shoes. consider getting a better amp. Crate, Marshall, Peavey, whatever you prefer.
