Hello Paulo!
good luck with your maiden, the plane is beautiful so let me answer your questions and give you some extra advise,
Yes, I am using the CofG recommended: it will look like a bunch of weight on the nose, but that is how it is...dont be afraid..to have a tail heavy Camel would be VERY bad.
Yes, same throws recommended. For the maiden flight i would recommend you use the High Throws.
Aileron and Rudder Mix. Yes, I use it after i noticed a lot of opposite yaw without it. So, Yes, use it. Although you will not crash without it.
Now, my personal recommendations:
-Elevator, use a 50% Expo.... it will keep the plane from nosing over on landing.
-Make sure you have a powerful motor (what motor are you using?)
-When you try to take off with the Camel, do not take off if the plane is acting funny..like wind cocking, Check this video of mine, look at the take off:

I think you will do just fine Paulo, but , dont push for take off. only go for it when the plane is tracking nice and straight, and for landing, dont land too fast, dont land too slow, and incorporate the Expo 50% on your elevator, it will help you avoid nose overs.
it is a very nice plane, but it must be respected,
Also, my kit when i put it together, the wing incidences were 'off ' . I had to crrect them. Did you check your wing incidences?
let me know how it goes??
