what are common oxidation numbers we should know, besides oxygen being 2-??

You can reference the periodic table and see what elements have however many electrons and whether they would prefer to gain or lose a specific number of electrons to fulfill the octet rule.

Also consider electronegativity when dealing with multiple group 5, 6 ,7 elements such as oxygen and sulfur. While both prefer gaining two electrons, oxygen is more electronegative so if the two were to react S would likely be +6 rather than -2

A general rule of thumb is that H will be +1 and O and S will be -2.
