The original post took me back to when I first started playing a shadow knight. I noticed you requested comprehensive lists, so I wanted to provide some lists, following the fine suggestions that you have already received. Since many websites have vanished, it would not be a bad idea to copy and paste information so that you will not lose it.
lordtweak mentioned the benefits of trophies. Here is a comprehensive list of trophies from Fanra. Just click on "Trophy Spreadsheet" The trophies with the best armor class are highlighted in yellow.

Katiekaboom mentioned the benefits of heroic alternate advancement. Here is a comprehensive list of the heroic AA achievements from Fanra.

Katiekaboom also mentioned type 5 augmentations. On the EQ Resource website, if you open up an expansion page, you get a searched list. This is the one for The Burning Lands. Depending on your build HDEX, HSTA, or HAGI, you can fill all of your type 5 slots with them. Some are lore, but some like the Mortal Corporeal Deft Zephyr are not , so you can buy as many as you like with currency from the missions.
The type 7/8 augmentations are also important, and once again, EQ Resource can give you a list with their links (this is TBL), although it seems to contain oddball entries. Most are obtained from killing named creatures, but some are crafted. You can either make them or buy them in the bazaar, but you will need a muhbis to complete it.
wymranar mentioned the type 18/19 augmentations and the four evolving items from the Fight Fire missions. At the bottom of the Fanra page, the links to the four items are listed. As for the augmentations, EQ Resource has a link for them too.
