apu panel  located near the cockpit door, beneath fuel dump panel. its by the right F\Es hand.

as for trim - its simple. goto fsx controls, control surfaces, find ELEVATOR TRIM buttons, and decrease REPEAT to zero. trim still be very sensitive, but at least you wont hit it twice the same click.

another way is to do that in aircraft.cfg:

change this - elevator_trim_effectiveness = 1.0
to that - elevator_trim_effectiveness = 0.3

this solution fixes trim problem BUT!! since it still uses same gauge, trim position indication in VC will be WRONG! so you cant set it by table.

its up to you to choose) i've flown with both fixes. second fixes it completely, but you gotta takeoff somehow - and that a pain:) So now i use first solution. got used to it. work fine on takeoff. and i do a lot of hand flying :)

cant say for F models. i dont have em :)
