Here's what's happening:

1)  Delete { Surface{122, 124, 126, 120}; } : you cannot delete these surfaces - they are embedded in the volume. The error message is bad - this is now fixed in SVN.

2) Disappearing entities when you merge the .step file in the .geo file : this is "normal" in the current version, you need to explicitly call "SyncModel;" before the "Merge", so that the .geo model gets imported right away in the model database. Otherwise the .step gets imported with entity tags that can clash with those used in the .geo mode. This explicit sync step is indeed a bit annoying -  the SVN version now does it automatically.
