As for the 10K resistor you can measure the coil resistance with it connected. With the resistance of a good coil being so low 20 something ohms 10K isn't going to effect the reading very much at all. If your coil is open you'll be measuring the 10K resistor not the low value of the coil.
If it is it's not as fussy as the osc coil direction of the winding doesn't matter and number of turn isn't real critical either. 20 turns or so should be fine.
