If you are not using a stepper driver you should remove it.
note: You also should remove them if you are powering the board with out motors attached. Say for flashing.
Your crimps are fine but not needed for the screw terminals.
If you want to run the board without having a heater plugged in you should be fine as long as you don't call for heat.
If you are worried about it just leave the HB-PWR wires disconnected. The board will function just fine without power to the HB circuit.

Hope this answers your questions.

Also, if i do not have a heated bed plugged in, will it matter if I turn it on? (I really do not want to make a mistake)

How does this look for crimping?

How does this look for crimping? Also, if I am not using a stepper driver, should I take it out?

Don't use the 5sb wires.

2x 12v to heater bed +
2x GND to heater bed -
1x 12v to the other + (main)
1x GND to the other - (main)

Okay, so from the picture above this is my plan to wire up the RUMBA.

I am checking in with guys first to make sure do not do anything that will cost me my board. What do I end up doing with the 3 ground wires?
