Yes: put libmysql.dll back into the c:\php\ directory and make sure it is NOT left in the system32 directory.
Next, I'm a bit confused; are you saying that the two extension= directives you mentioned above on the same line in your php.ini config file? If so, they certainly should not be - all of the extension= configurations (as well as all others in php.ini) should be on their own line.
Finally, make sure you add c:\php\ to your system's PATH environment variable as per the installation instructions in the PHP.net manual (see: [man]install.windows.manual[/man]). Once you've done that, you'll have to restart your system. Once it's restarted, do a phpinfo() and see if the mysql and/or mysqli tables appear.
