plans for tomorrow

i'm confused using the prepositions like
On, to, in, into, onto, at and so on.

Please correct.
"Today my brother came in to my house to remind me that my son has a class meeting at 9am tomorrow. So, i have to wake up early for tomorrow. Before i go to the meeting i want to cook a breakfast for us. I'm planning to cook ham, hotdog and fried rice. Oh i didn't notice it's already after midnight! I have to sleep, goodnight!
