Filter past them
1. Leave yourself room in front, you shouldn't be within a car length of them if you are having trouble stopping.
2. Rev a bit more on starts and slip the clutch. It's a wet clutch, you won't break it as long as you aren't dumping it from redline.
3. Use your rear brake. On Hill starts, keep your foot on the brake until the bike starts moving forward. This keeps you from rolling back and may help with not stalling.
4. Filter. It's illegal, I've been pulled over and given careless driving tickets, but it's always an option. You should be comfortable on the bike first though. NJ lanes are not very wide and you are usually riding within inches of car mirrors on either side.
