Try to competently remove the HighResTexturePacks and download this instead http://skyrim.nexusmods.com/mods/9080/?. Also try a new game or a new installation of skyrim ( remember to remove the My documents Skyrim folder.
Yes (at least i think so). All mod downloaded throught NMM are stored in Mod-downloads. Also for clean install also delete your Skyrim folder in your Documents.
