All I ended up having to do was to uninstall 184.108.40.206 and reinstall the 220.127.116.11 and it worked with no issues. Amazing app and it's basically free because they bundle it with the reader.
I just installed True Suite on my T420 with ML 10.8.2 and it works out of the box. I don't recall installing any kexts that control the fingerprint reader, so I can't really help you there, sorry. Thanks for introducing me to the Suite though, it's amazing.
So the only thing that does not seem to work right now is the SD Ricoh reader. Have not tried the eSATA yet.
My T520 even works with the replicator and to any output device I choose to attach - docked or straight from the laptop no video issues.
