Scronch:
Cookies- it depends on whether you mean the
index.dat file has a modified date, or there are
username@sitename.txt files that are modified. If the former, that's no big deal - those are system files, they get refreshed automatically. If the latter, I don't know but I would be parannoyed (joke) and run antivirus and trojan scans (not a joke).
Directories- All Users and Default User are standard directories - I don't recommend altering them, except for moving Start Menu shortcuts or Favorite items if you feel like it. When account directories have WINNT appended, they are usually replacements (after you do a reinstall, etc). To further complicate your life, some 3rd-party applications are not smart enough to get the current user name and they wind up recreating directories with default names to put their Application Data subdirectories into.
Bottom line on this, IMO, is to ask yourself whether some extra dirs are irritating enough to spend hours of time researching, backing up, etc. and hoping you're not screwing up anything.
History- I don't use IE except for some testing, afraid I can't help with this one.
