So, a while back I made a spreadsheet to keep track of what quests I have completed, how many and what ones I have left to complete, what items I needed total for all of the quests, what keys I needed, and what quests weren't needed for The Collector. This was originally made in 12.3 shortly after I first started playing.
Since then, I have kept it updated with insight from the people who have used it, as well as any changes that were made to the quests/tasks from BSG.
This has now been updated for 12.6 to reflect the currently known changes to the item amounts needed for certain tasks, as well as what items that previously did not need the "Found in Raid" tag and now do.

If you find any issues, missing information, or just plain wrong(as I said, I'm still fairly new to the game, and most/all of the information pertaining to items, amount of items, and the quests, were all gathered from the Wiki and various other places) please don't hesitate to DM me or post a comment here.
EDIT 1: Added in the new Jaegar quest – The Survivalist Path – Junkie. Thanks to /u/tops132 for the information.
