Some good guides:
Gloves Weapons Boots Companions Destiny
Companions can be gained under Unburden Yourself to an Attendant storylet (which can be accessed through the main hub via Seek out the Attendants) by paying the right confessions + an un-upgraded version of that companion.
You can only get one of each upgraded companion, but as long as you have the base companion + confessions you can gain each variant of the upgraded companion. The available companions change each year making old ones impossible or FATE-locked.
