The first thing you need to install in SIMBL - (SIMple Bundle Loader) - pronounced like "symbol" or "cymbal" - enables hacks and plugins. Download it from http://www.culater.net/software/SIMBL/SIMBL.php Unzip it and use the .pkg installer.
Next step is to get the required plugins. Most of the plugins come with installer but it's easy to do it yourself. Plugins can be copied to /Library/Application Support/SIMBL/Plugins for all users or ~/Library/Application Support/SIMBL/Plugins for just your account.
