Try the built-in debugger: Evaluation>Debugger with Break at messages checked.

comment Is there a bug in MatrixExp in Mathematica v10?
Confirmed the issue in ver.10. For your example specifically, since the matrix can be exactly diagonalized using Eigensystem, you can get a nice analytic expression--I'm assuming it's used in quantum mechanics where the matrix is the Hamiltonian (easily diagonalized in your example) and you want the unitary propagator with MatrixExp.

comment Numerical integration and plotting
The OP wants to plot fC as a function fP, maybe like ParametricPlot[{fC[a],fP[a]},{a,0,5}]?

comment Combining 2D slices into a 3D plot
@Nick If you only care about the final output, you could, in theory, put the data of your 2D slices in a list and replace g=Table[...] with g=ListPlot3D[...] in my answer. It's not exactly stacking 2D plots but the end result may look the same. For example, one way to get the data from Plot[...] is here.
