Um. Don't think so. I've been rereading that era lately, and Spidey Sense started being used pretty early on for things like navigating in pitch darkness and the like. It did tend to be a bit more hit or miss in his first issue or two, but that went away pretty fast.
As for the webbing, I also liked the Rami solution, but also like the idea of the shooters. I sometimes thought a compromise might be to give him the organic webbing, but have Spider-Man design compressed air devices that let him shoot it further, and manipulate it better. But then, Ditko never asked me.
