2) So just the wrong word for people... What does человек mean then?

3) Why does пирог get an a on the end?
Пирог -- the noun of masculine gender ending a consonant. These nouns usually have а ending in genitive.

Also, shouldn't собакa be in accustive, or does a comma start all the cases over again?
Yes, "моя собака съела его" is the new sentence.

As for утром, is the м some special case modifier or was утром just misspelled?
Most of all neuter noun with o on the end are declined like this (окном, озером), but there are some exclusions, for example пальто, which has never declined.
