We used those same Anderson connectors for the power connections. They are no harder to crimp than the standard ring or forked lugs when you have the proper tool. Make sure you do a pull-test after each and every crimp.
We also used the latched connectors from Hansen Hobbies for the CAN connections, male on one pair, female on the other pair. We used the same crimp tool as for the "normal" PWM connectors. Kiet, one of the mentors for The Holy Cows told me the same connectors are available at DigiKey for somewhat less $. I believe they are made by Tyco Electronics.
