If there are more positions, there is often a washer on the mounting spindle with a tag which is used to restrict the number of switch positions.

You don't say what current you need to control, just make sure that the switch can carry the current (and more) and that the resistors have a high enough power rating.

Perfect.

Will measure the current to check when its running in its unmodified current state.  And yes, will make sure over the resistors.
