I hope the bottom bracket noise is nothing serious... 360$ was a steal. Just for your pleasure look at what 350$ can get you:
vélo 21 vitesses DIAMOND BACK | de route | Longueuil / Rive-Sud | Kijiji

Can be found here:
54 | Vélos de Route dans Grand Montréal | Petites Annonces Classées de Kijiji - Page 2

Anyway, I will get a bottom bracket wrench to tighten it up and see if the noise vanish. Otherwise I will open it and inspect.
