well, here's some rambling on what's already mentioned (any mods i mention can either be found at the source or the summit):
Morag Tong writs - haven't even joined the faction yet, sorry :/
NPC's stop in a doorway = Open console and use RA. yes, they go back to the doorway, yes it's annoying, but i haven't tried any mods for fixing this. I guess you just have to change their walking paths. i'm not a modder, but i don't think it's very hard.
footsteps - i turn the volume for footsteps down because the sound irritates the hell out of me. about 60% volume and I don't notice it very often.
character animation - sorry, can't help there. i find some of the animations quite comical, like when a character suddenly hops for no reason. this would require radically changing all the races in the game i think. if much could really be done at all.
hand-to-hand - already discussed. morrowind enhanced w/ combat enhanced or combat moves by ghanburighan
npcs not attacking when item is not valuable - a couple things. many of the npcs aren't adventurers. a typical person living in a shack has about 5 septims of pay per month. anything is valuable to them. in balmora, you're probably looking at 20 or so septims a month. adventurers are the ones with tonnes of money. 20 septims is quite a bit of money to a typical commoner.
another thing - if someone came into your house and stole your plates, or a beer out of the fridge, i bet you'd beat the <not sure of the rules on the board so i'll censor the expletives just in case. don't want to be kicked out this fast> out of them. i know I would.
dunmer - sorry, can't fix them. you just gotta try playing them differently. unless of course, it's not playing them that's the problem but their whole presence. in that case, get off their island

boots of blinding speed - i don't see the problem (no pun intended). with a little effort you can wear them just fine. (well, a little effort and a lot of money)
limited quests - yes, need more quests. all i can say is download quest mods. or somebody get to work writing quests for faction leaders x)
cliff racers - Passive healthy wildlife mod. or make them more challenging with Wakims game improvements. whatever's your fancy.
sixth house amulets and removing selected spell - ? i'd like to know myself. annoying...
bad speling - unofficial morrowind patch
http://www.ethereals...tm/download.htmvoices - vgreetings was mentioned. haven't tried it yet.
lack of people - balmora expanded, vivec expanded, morrowind comes to life (make sure you use fps optimizer or get ready for an fps hit)
leveling up too fast - first of all, make sure you don't have athletics, acrobatics, speachcraft, mercantile or security as major skills. next, don't pay to train skills (or use wakims game improvements so training is too expensive for the beginner). other than that, i would like to find a mod that makes more powerful (more mana intensive) spells level the skill up more than cantrips (1 mana spells). a 1 mana spell should only increase the skill by 1%, while a 20 mana spell might increase is by 6 or 7. greater diminishing returns to be seen for misc skills after level 50. i don't actually know of a mod that does that though...
also, for enemy's being to easy, try morrowind advanced. supposedly pretty good
i'm too slow (my own complaint) - level up strength. if you less encumbered, you move faster. i learned the difference when i started an orc with 30 speed and 65 str, and a mage with 30 speed and 30 strenght. hoo-wee
well, hopefully you find something in there to help you.
as a side note, i had roast beef for supper x)
