comment Interpolating Matrices
usually, you don't even have to extract the angle from the matrix, just interpolate BEFORE you construct the transform matrix.

comment Should I use Box2D for collision-detection only (not simulating physics)?
If you just get collision data and teleport your bodies around with setPosition, Box2D will miss the velocity, acceleration, force, torque and angular speed data, since you're placing the bodies by hand, and not letting Box2D do it's simulation job. For this, Box2D will not be capable of telling your collision with precision, but maybe some frames late, or even with wrong data, since the data missing plays a big part on the collision predicting it uses for dynamic bodies. Your alternative is to use the full simulation on Box2D, or not use it at all. That is, if you want a good game.

I don't see why this is a off-topic question, it seems pretty valid to me. But it is a duplicate of stackoverflow.com/questions/16309280/…, by the way: don't do it, it is going to look choppy and unstable, since the integrator is part of the collision detection on Box2D, that is, it uses the velocity, torque and acceleration data as part of the guess-work to detect collisions.

comment When using deferred rendering technique, what space should my normals be? Why?
Yup, that's one of the reasons too. View-space normals allow you to omit the normal Z and recalc it from X and Y. Thus using a single R16G16 to store normals efficiently and with more precision.

I still don't like the only answer I have, but I'm going to accept it anyway. If anyone gives a better answer, I'll change it if possible.

comment Is it a bad idea to couple action and animation?
What I fear the most of both of these options: I'd probably have to write some kind of external tool to author animations with events.
