We've recently upgraded a copy of a 100,000+ contact install running 2.2.8 to 3.0 b3 for testing purposes. Functionality is fine and things look absolutely great in the new interface.
The upgrade was painless and quite quick. There was a foreign key drop constraint in the installer that needs tweaking, but the core team is on it and apart from that it took only about 20 minutes start to finish to upgrade the fairly good sized database.
CiviCRM has included a plugin for interfacing United States Postal Services (USPS) Address Standardization web service for quite a number of releases. However, the USPS rules for using the service have been a bit hard to pin down and getting authorization from is apparently hit or miss. There have been a few forum posts indicating success using the plugin with CiviCRM versions 1.8 and possibly 1.9. However, since then we've pretty much only had reports of problems related to folks enabling the feature without having a valid account etc.
