Hey everyone - I'm still playing on vanilla morrowind however it has got a bit dull so I am wondering what mods i should download. Things that improve the game heaps, from graphics to npcs to buildings etc. What are the awesome mods that have been intelligently designed that really enhance the game-play? No game breaking mods...

My first mod (installed it yesterday) was better bodies. I liked it a lot. the Morrowind Code Patch is a useful one too but I suppose that one runs without you really noticing but enhances the game none-the-less. I haven't noticed any big differences because of it yet.

Well, It depends on what you count as "best" mods.

For me, it's essential to install first of all patch mods like the unofficial morrowind patch (the updates made recently, I think last version is UMP 1.6.5?? got to check that) and so on. Then I like to have a good bunch of graphical improvements, but here you have to choose what fits your tastes. And then City expansions, companions, there are too many kinds of mods for you to choose so my advice is that you:
-Check telesphoros list of mods, that's a nice place to start
-Check also the Hall of Fame mods at Planet elder scrolls
-Check Tesnexus too

It's a matter of trying mods until you find the ones you like best. Anyway I'll tell you some I use:

UMP 1.6.5
Children of Morrowind

Better Bodies (with Westly's textures added)
Better clothes
Nioliv's robe replacer
mesh improvements (customized version)
book jackets
Vurt's ascadian and ashlands trees replacers
darknut's armor textures and Darknut's little weapons
Arcimaestro antares big and small mods
Creatures x
pegas horse ranch
abot's water ife
abot's where are all the birds going...

Races, companions, quests.... I have dozens more. Check the lists, play with the mods you find interesting to see if you like what they do, and you'll find you own combination.

Good luck!! I hope you become a mod lover/maker/player like many of us here!! and excuse any typos, I'm still fighting with english heh
