I believe you are talking about a Sig Kadet LT - 25.
The O.S. .32 makes me think that you want it flying more as a sport plane than as a trainer.

aside from wing incedence and down thrust on the motor, is there much else to do?

Not really, but go in full playing with the incidence first (reducing the difference in angle between the wing and stab), and the thrust angle later (increasing thrust down if needed).
