now my question:
we managed to calculate the microstrip filter so that one is done and
simulated. what botters us is that we didn't get ANY sort of a course
(we have to find anything on our own) and we have no clue about the
coupled lines and even less about the interdigital filter.
there is very very little useful information to find on the web so
please can someone help me here by giving some basic
methodology/formulas for coulpled lines or interdigital filters. maybe
someone has a few pdf's or other info on his harddisk he/she could
send me?

Why are you only looking on the web? Does your school
not have a library?

There are zillions of papers on the subject out there.
I'd start with either RF Design or IEEE Microwave Theory
and Techniques.
