For this sort of model just go 0-0-0 and then include 1.0 to 1.5 degrees of right thrust to aid in counteracting torque effects. It's an aerobatic model after all. If it needs too much up trim following the new ''first'' flight which results in too strong a nose up pitch with added power then it is a sign that your CG is too far forward. Shift it back, retrim the elevator trim to compensate and you should find that the power on to power off trim change reduces. Shift the balance back in small steps with associated elevator trim changes until the plane is as pitch neutral as you can tolerate. By that time the model should be quite neutral and snap roll and do other such things cleanly. The 0-0-0 initial setup is prep for working the CG back in this manner.

If you don't want it to be that hard core than with the wing as the reference go with -2/0/-1 for engine downthrust/wing/stabilizer angles. The wing in this case being always zero because you're using the wing as the reference line inorder to avoid shape induced oddities with the fuselage. With this would be included 1.5 to 2 degrees of right thrust. This sort of setup would produce a good sport flying model but is not a good setup for extreme aerobatics or precision aerobatics where you want to get nice straight up and down lines and such things. The plane with such a setup would also end up with the CG set to be a little pitch stable rather than pitch neutral.

For the CG locations for each use one of the online CG calculators (links in the sticky thread at the top of the listings) to find the Neutral Point location and CG's for the stabilty values. For the 0-0-0 setup start at 5% stability and work things back until you're at or just a hair in front of the neutral point. For the ''sport'' setup I'd likely start with the CG at around 7% stability and work it back a little until you like it and the model seems to be happiest.
