I know you haven't asked, but many of us would recommend a first play through without mods, to get a real feel for what the devs intended and what you would most want to mod.

I would suggest that if you do still want to mod there is one that is quite popular and will probably address many, if not most or all, of your concerns.

Happy hunting!
