I answer this question by myself <img class='smiley' src='http://n4.nabble.com/images/smiley/smiley_beam.gif' />
First of all I followed and read twice all these tutorials:
<a href="http://cocoadevcentral.com/" target="_top" rel="nofollow" link="external">Cocoa Dev central</a>
After that I tried to build a couple of simple applications using XCode 4.2 and Objective-C.
After that I was able to jump back on Monodevelop and start to build my first Monomac XCode integrated app.
