What am I supposed to do before the baby is born?

I'm sure this is a stupid question, sorry, but my pregnancy insomnia is making me stupid.

I am hoping to breastfeed for the first couple months and then eventually combo feed.

Am I supposed to be looking for/setting up an appointment with a LC now? Or does the one in the hospital suffice? Am I supposed to be trying to collect colostrum after 37 weeks? Do I talk to my midwife about that or an LC? Where should I be starting in terms of learning about how to hold the baby to feed, cluster feeding, etc? Since I plan to combo feed, should I be introducing the bottle early or waiting until my supply gets established?
