https://www.dimensionengineering.com...bertooth2x12rc is the specs for a sabertooth - Outlaw is this the one?

The TZ85s are good, will have a go at programming one in a bit, but if you wanted to go down this route im sure someone could program them for you if you pay the cost for them from hobbyking.

the BEC would only be needed IF the esc do not have it, so depending on what you do with the esc you may not need to buy a BEC.

The BEC would fit after the jumper and fuse. May have its own fuse depending?
