You can remove the index.dat file by signing into another account, making sure all hidden and system files are visible and then going into the profile for the account that you want that deleted from and just delete it. It wil be recreated when you log into that name. You can get to it by going to Documents and Settings, User Name, Local Settings, Temporary Internet Files, Content IE5,
As for the files in the IE5 folders, those are cleared out when you use Internet Options in Control Panel and select delete files. The history files are cleared out in the same place by clicking on clear history.
