My guess is that Harbinger ignores the Normandy because it doesn't pose any immediate threat to him - he's got a whole field of little guys and vehicles running for the beam, they're the real problem at hand. What would he accomplish by shooting the Normandy, which is picking up survivors, and in doing so letting someone get to the beam?

As for the SR-2's landing - As long as the mass-effect field is active, shouldn't it be able to hover above the ground at low altitude? I think the statement that the Normandy can't land on planets means that it can't power off and "park" itself on the ground without using mass-effect fields
