I'll answer, but obviously I can be wrong. For the animal companion, you need to be level 6 ranger to get it, so whenever that would be (assuming your leveling as evenly as possible that would be lvl 11 yes). As for 'requiring' a CDQ, I assume its no(could be wrong but I don't think every ranger has run a CDQ to use their companion), but you could always request one if you wanted. Again not a GM so I could be wrong.
