Hiya
Really you should threadlock every screw that thas metal to metal contact and cyno every screw thats metal to plastic. Doesnt apply so much on a small electric but for sure you should be threadlocking the feathering spindle bolts... Good grief think what would happen if it came loose in flight

. Also, I dont want to be too alarmist here but the order of the bearings and washers in the blade grips is critical.. Seriously. With the bigger machines if you install the thrust washers the wrong way round, the blade grips can lock up under load. No pitch control very little cyclic control... End of heli.
Ive just taken a look at the manual and I see what you mean however, heres my interpretation of the order of stuff..
From the outside... Feathering spindle bolt, Small diameter washer, Bearing (or it might be a thrust washer), washer 5x8x0.1 (27), Small Bearing (there should be a recess in the grip for it), Small Bearing, Step washer 2x3x2 (20), O ring (25) (should be in the recess inside the headblock)
Like I say thats my take on it and it might be wrong.
The way to test this is to build it up as you think it should be and if the blade grips can move smoothly and easily (the usually drop by the weight of the control arm) then give them a pull outward in the directions the blades will pull them (use a fair tug and keep it on) then try moving the grips.. If they still move smoothly and easily, then its probably right. If it feels rough or it wont move easily the its likely somethings in the wrong place.
As far as places to fly goes.. yep, the farmer round here get angry too lol but Im a member of 2 clubs. One is a heli only club that rents a field..
