Booth was like an assassin he just went behind him and shoot. While Ulfric went up to him challenged him and he said yes. The Thu'um is not like a gun. It's a skill. Like a fighter knowing martial arts. So yes, he can defend Skyrim because he used his skills to win the fight.

You're basing that off of nothing. The Dossier does not imply such a thing, if Ulfric was indeed so hard to keep alive they probably would've said something about that. But only once did they say it would've been necessary. Yes Ulfric getting captured does say a lot about his abilites, it shows he actually does stuff. He doesn't just sit around giving orders. He actually stands by the people and fights with them.
