I have always personally felt that the default clothing textures, in both Vanilla and SI are a bit lacking, and don't have any real good texture replacers. Also, you know what is in desperate need of retexturing, is some of the wooden Luminar staffs from OOO, they are horrendous, and clash badly with the new textures for torches.
Have you looked at these:
Armor and Clothing Redone - http://www.tesnexus.com/downloads/file.php?id=27414 <-- I think I prefer this set
Paul's Clothing Retextures - http://www.tesnexus.com/downloads/file.php?id=33322
Cali's Female Finery - http://www.tesnexus.com/downloads/file.php?id=26850
I'd like to see Shrouded Armor retextured though.

Edit: more subtle...
Mike's Clothes Replacer - http://tesnexus.com/downloads/file.php?id=7487
Also, the link to the one Planes of Oblivion retexture - http://tesnexus.com/downloads/file.php?id=27887
Edit: Mythic animals, mythic creatures and a couple others by the same author are good high rez creature textures replacers
There are three for staffs (excluding Hromir's Ice Staff I think), and InsanitySorrow has retextured a few as well.
Edit: Actually, Visually Improved Staffs covers the ice staff - http://tesnexus.com/downloads/file.php?id=38438
I'm not using that, only using Hi Res Staffs - http://tesnexus.com/downloads/file.php?id=29412 ...along with InsanitySorrow's Improved Armory mods
