You should use ethereal (http://www.ethereal.com) to trace the
events on your network.

You do nothing. The protocol implementation does that for you.
You just use the API funtions, and respective callbacks.

On one PC you run a server. Look at discard_server.c for example.
On another, you run a client. See terminal.c for example.

I suggest you have a look at the RFC 2960, and especially
the section 10, which describes an API.
It might also be worthwhile looking at
http://tdrwww.exp-math.uni-essen.de/pages/forschung/sctp_fb/sctp_api.html
It might be a bit outdated, but describes our API pretty well.
Also, have a look at the manual, which comes with the distribution.
It is located in the "manual" subdirectory, and named sctp-api-1.0-1.pdf
