To give you an idea just how lightly my Sig Tri-Star sits on its nose wheel, it will tip back on its tail if I elevate it more than 2.25". My plane has a 48" wingspan. If I scaled it up to the 57" span of the long ez 46 (that is your plane's wingspan isn't it?) then that distance would measure 2.6". That should ensure that your plane is abe to lift smoothly off the runway without too much elevator input.

I think that end plates on the canards might adversly affect lateral stability so I'd try adjusting the C.G. and the main gear location first for your pitch control problems. My canard does just great without end-plates. Heres a crappy video of it. Its hard to make out but it will even do a Lomcevak (sp?) tumbling manuver.

I wouldn't mess with the thrustline just yet because that might ruin the plane's flying qualities. My c.g. is about an inch behind its recommended c.g.. You'll have to experiment with that on your plane to your own taste. Rudder control should be fun to experiment with. I was planning on adding that to my plane someday.
