Looks like a good start. Play with that for a bit to make sure it is stable and then look for mods. There is everything you can think of (even bikini armor if you can believe it

) so when you search look for what you want. When I am on tesnexus I browse categories, find the category I want, sort by downloads descending (get the most downloaded mods first in the list) and see what is there. Also tesnexus has top rated mods list which is a good place to look.
Consider using wrye bash in future.
On load order, the citadel door fix and vampire aging fix I would get rid of. Never noticed a citadel problem and never played vampire (but if you do then you may want to keep that). Wrye bash has these two fixes that can be imported into bashed patch so that is good. The fewer esp files the better seems to be the new thought.
If all is well with game consider adding Unique Landscapes, it makes the world nicer (look for patches with that as Kvatch rebuilt needs one). Try adding MMM for OOO to make it even more interesting. Redo interface with Darnified UI or Darn Dark ui. Glenvar is the best IMO plaer house and the quests are pretty good. Use the bank, the intrest adds up

The lost spires is a VERY GOOD quest mod, one of the best.
