Are you asking: What book, website? Or do you mean, with what case?
If the latter, then definitely nominative and accusative (singular and plural) followed closely by genitive singular. But I'm going on 34+ years of memory, so not quite sure what I learned first. The cases aren't really as hard as they're let on. Especially if you a) start with the standard endings (I'm thinking as opposed to genitive plural here) on the basic nouns (here I'm calling друзьями basic vs. людьми which I'd say is not) and b) learn what case each verb governs when you learn the verb and c) learn all the cases applicable to each preposition when you learn them.
You should definitely take up the study of this wonderful language? It's a very useful one to have in your language quiver!
