There are a couple of rules as for the stress: 1. ё is always stressed. So if you see ё in any word, you can be sure that the stress in this word will go on the syllable with ё. 2. There are masculine nouns that in plural have ending -а or -я instead of -ы or -и. In such words when they are in plural form, the last syllable with a ending will always be stressed: - докторА - поездА - домА - городА 3. You also might have noticed that many neuter nouns change their stress very often: - окнО - Окна - мОре - морЯ - слОво - словА Also I think usually long words with many syllables keep their stress at the same position in any form. But short words with one or two syllables change their stress all the time when you use then in different forms.

Sorry, no rules for stresses. You need to look into dictionaries. Also not all russian know where are stresses, so.. The intonations is not much different or any european language (roman or germanic) - rising up in questions and goes down in regular or exclamatory sentence.

P.P.S. Russian language stress isn't like France or Finnish. It's so difficult, yeah. And "(Alexander) Pushkin" stressed like p-U-shkin, not pushk-I-n. But we often doing stress on root in the word. For example: "обесп-Е-ченность (means "wealth" in this case) - you have to stress on first "E" (russian), because root of this word is "обеспЕчен". To do stress is easier beside russian case (7 cases of Russian Language).
