There's a plethora of mods, a real mess if you're not familiar with the nooks and crannies. An excellent (automated) mod package I can recommend is
Morrowind Overhaul. I re-played the game with version 2 some time ago. It looks gorgeous, although it also puts quite a bit of strain on the machine the more you max out the visuals. It's not only graphical, I think, but also includes some script fixes.
Spirit: aw, you're like a little puppy. As soons as the level starts, run to the room on the left for cover. You can pick off the enemies from there.
