Ah, you are right on the PRISM distinction, I mixed up details with the "metadata" thing, which I'm sure is not accidental. A lot of the responses from government officials are to the effect of "these aren't a concern, because to get the metadata we need to go through FISA courts for every individual", which is just a red herring now.
So, there are:
1. NSLs, published on the transparency report
2. FISA orders, which are "through a court", but is by all accounts just rubber stamping, not on the transparency report
3. PRISM, which is intended to bypass FISA entirely, according to the Guardian article. Either Google is lying, the NSA is doing it without Google's knowledge, or there is subtle wordplay involved (so, lying). Or, that it's been grossly misreported.
