I am getting some of the same errors. I got the e-mail yesterday with the 12-digit code and downloaded the 6gb what i assume is the installer? There is no way it's only 6 gbs, phase 3 was 14gb. Anyway, after the user agreement and the Square-Enix account have been entered, it comes up that I need to buy the game from the PSN to continue, as it doesn't detect an active service account. Ugh, I just want to get this ball rolling. I hope I don't have to wait till 4 in the morning to figure out what I need to be doing here to play the beta.
Edit: I just found this, which pretty much sums up what is happening. I sure hope they get it fixed.
