What is the conjugation of two derivatives of "venir", "parvenir" and "convenir" in Le Passé Composé?

Après qu’il fut parti, tu détruisis toutes ses affaires. 

What tense is “il fut parti”?  It appears to be a compound tense with the auxiliary verb in passé simple. 

to replace him was "Elle a dû" vs if it was inevitable, shouldn't "Elle devait" be correct as well?

I just wanted to say that the video in this lesson was super helpful. I struggled so much with this concept and now I get it right all the time. So, thank you!

I am a bit confused with the following sentence. The correct thing is to put ce que but instead, in the lesson, we know that ce qui should be used when the next word is a verb or an object or a reflexive pronoun?? Is it because, the "tu" is in front of the m' that doesn't count? Because I assumed that since there is a reflexive verb I should put ce qui. 

Thanks, 

Anna

"Ils avaient fait..." 

"Il avait fait..." 

These two sentences sound same. Is there a way that we can understand the correct sujet?

Chris' comment below about modal verbs (All modal verbs, like pouvoir or devoir require the infinitive, no matter which tense or mode they are in.) was an eye-opener for me as to how pouvoir and devoir fit in the big picture. Perhaps a short paragraph about modal verbs in general would be useful to others. Thanks!
