The dog should definitely be neutered. It may help with the aggression or it may not; it depends on what is causing the aggression. My friend had an aggressive GSD, he had been extensively socialized and was friendly and confident as a pup, so it wasn't a fear issue. He was just a hot-headed, macho, dominant brat whose owner had been too lenient with early signs of aggression (and in fact encouraged it).
He was MUCH more managable after being neutered. It didn't help his dog-aggression much, but he was a lot more controllable and predictable, and didn't fly off the handle like he used to. I think neutering can take the edge off an aggressive dog and make him more amenable to training, but it isn't a magic bullet. You still need to see a good trainer or behaviorist to address the aggression issues.
If the aggression comes from fear or insecurity, neutering probably won't help, but such a dog should still be neutered.
The surgery should not be terribly traumatic for a young, healthy dog. It is a fairly simple procedure, much less invasive than a spay, and most dogs bounce right back after a couple of days. Remember that it takes around 6 weeks for the hormones to totally leave his system, so any behavioral effects won't be noticed right away.
