Alright- I've figured it out. I'm not even remotely bright, but here is the problem:
The reason that autocomplete keeps filling in the websites and bringing it up as a "top hit" and suggesting things is because you have a link to that site saved in your bookmark folder.
STEP 1: DELETE ALL THE SITES FROM YOUR BOOKMARK FOLDER THAT YOU DO NOT WANT TO SHOW UP IN AUTOCOMPLETE.
STEP 2: Clear all history, restart Safari, and WALLA- Autocomplete shows NOTHING.
YAY!!!!
