I was once at the exact same point you are. And what helped my the most
was the Kamailio Advanced Training course. If you don't want/cannot to
do that, there is a kamailio-advanced.cfg provided with the
sources/packages.  That does all you want except dialplan and dialog
modules. Start by dissecting that config. 

Start small and build up the config. Just about any question you might
have is already asked and hopefully answered on this mailing list, so
search the archive and ask what you can't find/understand/figure out. 
There might be some answers in the cookbooks/tutorials on
http://www.kamailio.org/wiki/start#cookbooks

BTW I still use asterisk for upstream SIP trunks, it's b2bua features
can be really usefull when talking to the outside world. So again start
small and have kamailio talk to your existing asterisk machines (e.g.
via the dispatcher module) to reach the outside. Verify your kamailio
CDRs (extraced from the accounting module) to asterisk.
