Does Bachmann have insulated rail joiners like Atlas does?

After 20 years I am finally setting up my n scale. I purchased Bachmann's First Railroad Track Pack with video. I also purchased an MRC Tech 7 AMPAC 780 train controller. I decided to expand the First Railroad Track pack with additional track. What I want to set up is 2 mainlines each running separately tracks with a switch connecting both and the MRC has dual controls.
1. Do I need a re rerailer for each track for power ?
2. With eze-track, do I still need a connector(instead of a joiner)even though the eze-track has built in joiners?

I was waiting on the phone with Bachmann for over an hour on hold until I gave up. Please help. Thank you
