I gathered it like this. Shaw can only absorb stuff if he's sanely aware and by his will. Meaning when the grenade went off he had to willingly absorb it. However if he's sleeping and his room explodes he'd probably die since he wasn't prepared for it. Make sense?
Shaw absorbing the explosion is different, as he actively tries to gain the energy around him. When energy directly strikes his body, he absorbs it automatically. When he was getting hit with bullets from all directions, he didn't have to do a thing, nor could he be aware of where and when the bullets would hit him.
Now, if somehow his powers were "turned off", the slow moving coin would not have entered his skull at that speed. Instead the coin would just push his body back. Watch X2, where Xavier brain freezes everyone in the mall. One of the mutant kids pushes a mind-frozen bystander, and the person simply wobbles.
Now, the only reason Shaw could've stayed in place while the coin pushed against him, was if he was actively using his powers, including his super-strength to stay in place. However, this is a contradiction. If he was using his powers (assuming he has to turn them "on", which he doesn't, then he should've simply absorbed the kinetic energy of the coin). Also, Xavier explicitly did not want Magneto to kill Shaw, then why would he make Shaw hold himself in place with his super-strength, thus allowing Magneto to kill him?
I'd say it comes down to the writers not thinking it through thoroughly, or assumed the audience wouldn't. Either way, from what was shown about Shaw and his powers, he should not have been able to be killed that way.
As for the fight, there really isn't much Magneto can do to Shaw directly. If it started up close, assuming Shaw has some energy to start with, can just make the ship explode. The idea of Magneto levitating up and taking down the ship immediately does sound viable to me. However, I don't think Magneto would do that straight up. He has a personal vendetta against Shaw, he would want to kill Shaw in a more intimate manner.
I think this setting favors Magneto. Perhaps on land, in a city, it would be a more epic fight.
