The judicial branch regulates itself. Congress establishes courts, but the Judicial Branch provides for how they should be run.

Well... Congress has passed laws impacting venue decisions, and Congress can change the composition of the courts, for instance by adding new judgeships. Congress also creates special administrative courts like FISA.

It would have been clearer for me to say that judicial branch does its own administration, which includes rules on everything from procedure to publication of court decisions.

Congress prescribes plenty of procedural rules. It hasn't in the specific issue of publication but that doesn't necessarily imply that they couldn't.
