you may have a look at my book "Mathematica und C in der modernen
Springer-Verlag 1997, ISBN3-540-61489-3
It includes seven MathLink programs even for some complicated tasks and
it has a
chapter and the C- source for some high quality initial value solvers.

Yes. I principle you can almost everything with MathLink. What you plan
the opposite of the usual task.
Typical one uses the MathLink program for fast numerical solution of the
differential equations and Mathematica send the parameter to the
MathLink child and display the results.

You should load a package. The Notebook is a use a useless overhead.
Because you need the definitions in the kernel it is better to use a
package and load it via Get["somedefines.m"]
You can simply add a Evaluate:Get["somedefs.m"] to your C-code and the
package is loaded.
Hope that helps
