It's actually not that slow. By default, it's shooting at 72 rounds per second, and dropping it down to 30 rounds in one second didn't seem so bad to me, since the overall DR was still going to be bumped up to 4 anyways. Post in that thread so I can keep track of the feedback if you can please.
As for the implants, I've double checked and the only one we get standard issue is the brain spider. Which, despite being a staple, I don't think has an article of its own. You'll have to assume your character is either checking his datajocky, or is wearing an earbud that's connected to it.
