I am nowhere near my install right now, but in principle there ought to be a directory named something like:
c:\Documents and Settings\Username\Documents\My Games\Bethesda\Skyrim\Data\Override\ where you can install your mods.
c:\Documents and Settings\Username\Documents\My Games\Bethesda\Skyrim\Data\Override\ where you can install your mods.
wait a minute.
As far as I remember you don't install mods in your "my documents" folder, you install it in the game directory.
In the case of Steam this is an example ( I keep my Steam on D:) of the path to install let's say a texture mod:
D:\Steam\steamapps\common\skyrim\Data\texture
I need someone to confirm this for me, cause I want to know if all of a sudden things have changed for Skyrim modding from Oblivion.

but theres a caveat, anyone installing steam for the first time from the DVD will not get the option to install steam elsewhere - gamesass steam installer is different ....
