Those are called flux rings. They're standard on pretty much all motors. They close the magnetic loops in the core so the flux doesn't need to escape into the air to find its way back to the other end of the coil.

Power rating of a motor is the mechanical power out. Divide that by efficiency and you should roughly get electrical power in. Efficiency will be different if not at full-load. To get 6W mechanical @ 60% efficiency, you have to put 10W electrical in.
You have a problem. Driving motor correctly means generator is going in the incorrect direction, which ...

Kv is for back EMF. It is part of what you need to model the current, in addition to the resistive and inductive model of the motor windings. The current then gives your torque via Kt. This is all to a first approximation.
Here's a paper that describes the model, in Section II.C, equations (1-3)

Your definition of $K_t$ seems a mistake. By definition, the torque constant is simply the slope of $T (Nm)/i(amp)$ curve of a motor, and It should be noted that the parameter $K_t$ is not related to the voltage under which the motor is operated. If you use the motor at 12VDC or 24VDC this constant will remain the same. This attribute of the motor is very ...

If we ignore the weight of your lever you need 1/4 force to lift anything hooked at the short end. like to lift 100kg you need 25kg force.
If you want to calculate further you need to have the data on the weight of the lever, loading, speed, etc.

Calculate the moment of inertia of your lever. If you can't do the maths then use a 3D CAD package to draw it and use the mass properties tool (or whatever) to show the moment of inertia (and a load of other useful stuff). You'll need to specify the material density. OnShape is free if you don't mind your designs being public. See their mass properties help ...

Yes but it's not likely to be fully representative. If I were doing it, ? would be an integrated charging circuit around the 12V that includes the HSG and the inverter converter since it also charges the 12V off the ICE through the G of the HSG. The DCT might be something else as well (see 3)
Not likely. the MG is specifically for that. Again if I were ...

The product description page for the chassis says the motors have 6.6A stall current. It also explains that the three motors on one side are wired in parallel, so you need a two channel motor driver (or two single channel drivers) capable of supplying >20A per channel.
The Sabertooth driver may be expensive, but it is what you are looking for.
