I'm looking to come up with a list of recommendations similar to http://www.theassimilationlab.com/toql-the-oblivion-quest-list/wiki/The_Oblivion_Quest_List so I was wondering if anyone had any suggestions for quest mods.

Oh, brilliant idea. Thanks for thinking about this, deaths_soul Here're some threads that look like they could be worth a look:
http://www.gamesas.com/topic/1453137-large-quest-mod-recommendations
http://www.gamesas.com/topic/1415393-can-anyone-recommend-any-quest-mods-for-morrowind/
http://www.gamesas.com/topic/1196775-best-quest-mods-to-play-in-the-game-2011/

And there are some oldies but goodies on http://www.mwmythicmods.com/telesphoros.htm#29.
