To really clean things up try to:
- empty the cache_* tables in the database (cache_extensions contains 
the list of extensions in TER, so you can leave that one alone)
- clear typo3temp and its subdirectories
- remove the temp_CACHED_* files from the typo3conf folder
Maybe you can perform the previous steps from outside the TYPO3 
environment (from a control interface of your hosting package / command 
line / etc.)
- after those steps clear the browser cache and login to the TYPO3 backend

Now the site may be a bit slow because all the data has to be recreated 
which is normally cached, but if the installation of 4.3.x was done 
correctly it should look like TYPO3 4.3.x...
