It is probably too late to help now, but the game stores a list of your active mods here: c:\Users\<user name>\AppData\Local\Skyrim
At least if you have Windows 7. I am sure it is slightly different with other versions.
I am not sure if NMM or Wyre does this, but OBMM has a feature where you can use it to look at a save game, and it will create a list of what mods it is using. With the click of a button it will even automatically activate all of them that are turned off. At least if it is installed in the first place. But even if it is not installed, it will still give you the name of the mod and tell you it's not present. I find this helps immensely with juggling mods between characters, as well as when I had to reinstall Skyrim last year when I upgraded to a new computer.
Wrye does exactly this for Oblivion. Haven't tried it for Skyrim yet, sooooo. But I'd be surprised (very!) if it doesn't.
