You could always make the argument for the much feared 'depressed-trajectory' launch but honestly I think that was mostly theoretical. Not that it couldn't be done (launching SLBMs at ranges well below their maximum to cut-down on flight / reaction time in hopes of taking out enemy command and control or doing a counter-force strike on their bomber and ICBM bases), but that the Soviets were actually considering a 'first-strike' role for their SSBNs.
From what I recall reading, most of the SSBNs which would have patrolled close to the East Coast (like C-Wolf mentioned) were the old Yankees, and they were there because it was dictated by the relatively short range of their missiles. Further more, these 60s-era SLBMs probably wouldn't have had the accuracy to really accomplish a first-strike mission (i.e. knock-out or completely destroy the counter-force targets she'd likely be aiming at, in hopes of blunting / disrupting the American second-strike response.) so I think the whole thing is basically a non-starter which was more of something that the US was scared / paranoid about what could happen vs. a valid tactic that the Soviets actually planned on using.
As far as 'SSBN Wolfpacks' go, while I do remember hearing that the Soviets frequently escorted their boomers, I doubt very much they'd do it in a large numbers (multiple boomers and multiple escorts), especially for something getting sent out into the Atlantic because I think it would just be too easy to detect and put them into an 'all our eggs in one basket' situation. You could say that's exactly what they were doing by staying in bastions, but in that case it was their basket.
