No I don't think that just one step colder plugs (right?) would cause any difference in warm up or driveability...especially since you are running that Jacobs ignition. So what did you end up gapping them at? As for a rough acceleration you may want to recheck your timing. When was the last time you changed your fuel filter...cap & rotor? Sometimes it's the simple stuff.
