Please tell me there's an easier way.

When all else fails, read the instructions. Remember the little plastic cup with the slot in the side???? That's what you use to set your pinion. There is a specific instruction in your manual that shows you haw to mount the pinion.
The motor plate can be a problem if it rotates on the motor when you're installing it cause the holes then won't line up. Use a 3mm machine screw that is at least 30mm in length and remove the head. Put on the motor plate, then thread in the screw one or so turns. Line the screw up in the chassis and seat the motor. Install the other motor screw, then remove the screw without the head (it should be long enough to grab and turn) then install a motor screw. The screw without the head should keep the motor plate from rotating and will align the motor for you also.
The other alternative is to use the aluminum motor mount and leave out the motor plate.
