OT: Lawyer Questions (Leach)

Ok, a couple of questions for the lawyers. I know Texas law is a little different than other states, but I don't get what either side is arguing here.
First--Tech is arguing sovereign immunity. So that is where you can't sue the government for damages, right? But that doesn't mean that you can't sue the government for money that they are contractually obligated to pay you, does it? In other words, if I have a heart attack because I got a bad batch of swine flu vaccine from the government, I can't sue them for $200 mil, but if I am under contract with the government to do $50,000 of work, they can't just not pay me without cause and claim sovereign immunity, can they? (I suppose I get that it would be worth a shot to see if they can get the whole thing thrown out under sovereign immunity, but their real argument should be that they were in their rights to terminate Leach with cause, shouldn't it?)
Second--Leach is arguing for whistle blower protection? This makes no sense at all. Do you get paid for being a whistle blower? I would guess that you would get some of what you were under contract for, but he was the one who had the whistle blown on him. I would think James could get whistle blower protection if they tried to kick him off the team and take away his scholarship, but Leach? I thought whistle blower protection meant that if your company was doing something nefarious, you could go to the FBI and turn them in without fear of financial/professional repercussions for bringing it to light. Tech's actions were all pretty out in the open, and Leach was already fired. How does that make him a whistle blower? I could see a suit for breach of contract and trying to claim he was fired without cause, but a whistle blower? I don't see how that makes any sense.
