In the last sentence, "nous nous écrions : "Bonne Année !", why is the verb reflexive, or, why is the second nous, needed?

 Il se lave does that become se lave-t-il?  And while we're at it, il adore becomes adore-t-il, but il t'adore becomes  t'il -t-adore??

La parade is used as translation for the parade.  Is using le defile (sorry, can't get the accent aigu on the e's) incorrect? I don't even see it as an option in any of the possible translations listed.  

Pour etre riche, ____ beaucoup d'argent.  I put "il faut avoir" and it was wrong, "il faut" being correct.  Do we not use the infinitive here?  It doesn't seem right in either language.

Mélanie joue plus que Karine aux cartes. which is marked wrong seems to me to be just an inversion of Melanie joue aux cartes plus que Karine which is correct. Is this just one of those things the French dont do, or is there an underlying reason why the first version is wrong, please?
