Will,
For travleing through NJ:
You should be ok on the NJ Turnpike if it is early in the morning, right after sunrise. It's probably the only time that road doesn't have any traffic. I don't recommend it any other time while in a deuce. Alternate northern routes instead of the NJTP are Route 130 or I-295.
You could try I-295 which generally has less traffic but will only get you up to Trenton. From there, you can take get back onto Route 130 up to Route 1. If you took Route 130 from I-676, you will see alot more traffic lights but there are stretches that are very rural. There are traffic lights but the max speeds are 50-55. Route 1 will take you up to Newark Airport where you can get on Route 9 and take that up to the GWB. (I believe routes 1 & 9 are the same at this point) t wil be a slow trip going that way. The NJ Turnpike is the fastest route but not necessarily the safest.
Or, you could wrangle a few mv owners into providing you a convoy!
Just my 2 cents
