Sounds about right. Off the top of my head it goes: production order, broadcast order, and JMS's recommended order.
None of them actually work, but that's just how much TNT borked the internal continuity. I think I generally go with JMS's order, but just ditch 'Warzone' (no great loss) and start with 'Racing the Night' as was intended.
He can't. WB controls everything besides the movie rights, and supposedly it's been made clear that for various reasons (mostly the asinine way WB's divisions actively complete rather than co-operate) there's zero interest on their end with doing anything B5 ever. So unless there's a major shake-up, regime change, and/or fundamental reordering of the company's entire corporate culture; what we got is what we got.
