The only problem I ever had with Venom was how often he was in the comics. It seemed like every other month, he had a story. To be honest, Spider-Man has much more interesting villains than Venom. Mysterio, Scorpion and Arcade to name a few(that last one's a joke for those who know the comics
). But that doesn't mean I wouldn't want to see Venom.
By introducing John Jameson, there's potential to bring in the Man-Wolf, but I doubt it.
Scorpion would be awesome. That would mean more Jameson, and in turn, more J.K. Simmons, which I'm always up for. Mysterio would be absolutely fucking awesome. You could actually make some scenes creepy, but I doubt Raimi would do this.
