Hi there Oneworld,
As a current 75 driver I will try and fill in a few blanks.
This is all fairly generic to jets with underslung pod engines, as such with any power change there is a change in trim. i.e. if you increase thrust you get a pitch up, and vise versa thrust reduction pitch down.
So far as flying the sim, pay close attention to the pitch attitude, this varies on thrust and flap settings, but the key thing to success and smooth flight is a instrument scan with emphasis on pitch attitude and vertical speed (this helps you pick up any divergence from your flight path)
The thrust setting of 1.18EPR for the ILS is another one to remember.
Finally remember due to the size and mass of the aircraft (sim) it is important to keep pitch changes small.
Goodluck!
