Whatever you do, don't install Claralux and Imaginator from that list. They will destroy your savegames, as I experienced firsthand a couple of months ago. Those mods were really great before but are currently unsupported and do not go well with newer stuff. In my game they caused the light to go up to crazy supernova blinding levels, followed by savegame bloat and death.
Currently in the process of modding Skyrim from scratch again, it's a lot of work, but I really wish to do it right now.
If you plan to do the same, you should take a look at recent guides like this: http://www.nexusmods.com/skyrim/mods/50244/?
A lot of mods came out recently that make Skyrim more stable with lots of highres mods and prevent CTD.
