It's time to install mods again, because my previous modded game was a big buggy and unbalanced mess. Yes, I could do some diagnostic and fix it, but it is cool to start new playthrough with better mods and gameplay.

I want to overhaul Skyrim as much possible, to change it into an interesting RPG experience. But also not transform it into an unbalanced mess or artifacial difficulty game.

General overhaul
Perkus Maximus with SkyRe Zones Module (it's recommended in the mod)
Trade and Barter
Complete fast travel overhaul
Frostfall

Can you recommended some more cool mods for gameplay?
Which mod should I use for improving sneaking?
Any enchanting and alchemy mod?
Which equipment degradation mod is better? http://www.nexusmods.com/skyrim/mods/55677 or http://www.nexusmods.com/skyrim/mods/32057
Maybe there's a mod (project?) to overhaul vanilla dungeons? I don't believe, there's still not one.

Combat
Combat was broken in previous playthrough - bandits were too strong and could kill me in two hits, even on easiest difficulty, creature were very weak. It was driving me to huge frustration. I don't know what caused this problem, rather enemy changing mods than combat ones.

I'm going to use these mods:
Ultimate Combat
Action combat
Combat evolved
TK dodge

Should anything be replaced? What settings should I use for these mods?

Share you suggestions.
