Yes 4.3 came with the iPad 2 when it initially shipped. 4.3.1 was released within a week I believe and units started shipping with 4.3.1 within a few weeks of initial launch. As far as the seller having saved shsh blobs I do not know if it would be an issue since you would be loading it on a different computer and a new iTunes account. As far as I know there were no performance/new features with the firmware updates. 4.3.1 was to patch the exploit, 4.3.2 supposedly fixed connection issues for some Verizon 3G models and 4.3.3 was the update for no longer saving the cache of location services. To verify the firmware, go to settings-general-about-version.
