SKSE is right here, and you need what it does for SkyUI to work:
http://skse.silverlock.org/
People are always apparently screwing up how to install SKSE, so here’s a walkthrough on doing it right.
Grab the current SKSE build. As of me typing this, it’s 1.06.05. Download it to your desktop or somewhere convenient.
Find the directory where you installed Skyrim. If you just straight-up installed Skyrim with default choices it’ll be in
X:\Program Files\Steam\steamapps\common\skyrim\
or
X:\Program Files(x86)\Steam\steamapps\common\skyrim\
All depends on your OS I think, and “X” obviously is the drive letter where you’ve got Steam installed. At any rate, you want to find the directory that has TESV.exe and SkyrimLauncher.exe in it, along with a bunch of other stuff obviously.
Open that directory, and stick the zipped SKSE file you downloaded into it, and then rightclick and “extract here…”
Once you’ve done that, find the file called “skse_loader.exe”. That’s your new executable file to launch games of Skyrim with. You can launch with TESV.exe or SkyrimLauncher.exe, but you won’t get the benefits of having SKSE running, and any mods that depend on it won’t work right. You can rightclick skse_loader.exe and make a shortcut for your desktop, or if you eventually decide to start adding more mods, both the Nexus Mod Manager AND the Mod Organizer utilities both will let you set up so that you launch the game with skse_loader.exe running.
Hope that helps!
The rest of the mods I listed can all be found under those exact mod names at the Nexus.
Categorized Favorites is here:

When you tag items to come up as “favorites” (spells, shouts, swords, bows, arrows, etc.), it puts them into easy-to-find and access categories when you pull up your favorites.
Better Dialogue Controls is here:

Skyrim has this annoying tendency to occasionally select a dialogue choice you didn’t mean for it to. This fixes that. Simple stuff, but really great. (Yeah, I listed the name wrong earlier; my bad!)
Better MessageBox Controls is here:
http://www.skyrim.nexusmods.com/mods/28170
Skyrim sometimes does the same thing with message box choices. This fixes that.
