I just bought it what are some mod suggestions? Anything that makes the inventory more like Oblivions? Good armor, clothing and weapon mods? Any magic mods that add Morrowind spells back in? New perk trees possibly? How about any other game play improving mods? Voiced Quest mods? I love Midas Magic in Oblivion so I will be picking that up for Skyrim for sure.

You should play vanilla a while so you know what the game needs from your own perspective and preferences. That said, arrow auto unequipper, crimson tide, better horses, mighty magick, deadly dragons, frostfall and skytest animal overhaul are some of my "must have mods".

I definitely have 300+ hours logged on the 360 version. Think I know how to play

I also have Morrowind and Oblivion on PC so I am not new to mods.

Just looking for suggestions and you gave some, thank you I will check them out.

Is SkyUI compatible with an xbox controller? I would like a UI like it that I can use the controller for.

In addition to SkyUI, I suggest http://skyrim.nexusmods.com/mods/4929.

I believe it is supported. Don't know how well it works, though.

I made the move from Xbox to PC.

I would suggest...http://skyrim.nexusmods.com/mods/12964 I use the "My Config" version. And yes, it works well with SkyUI.

Immersive HUD http://skyrim.nexusmods.com/mods/3222
Natural Favorites Expanded http://skyrim.nexusmods.com/mods/5229
Skill Interface Retexture http://skyrim.nexusmods.com/mods/7308 ( not an essential, but pretty amazing )

There are recent threads that give other suggestions here. http://www.gamesas.com/topic/1396155-mod-recommendations-for-a-new-pc-player/
