Asgardians, both movie and comic wise, all have super strength, speed, and durability. Thor is simply one of the strongest.....in both movies and the comics.
From what I can tell, movie Thor and comic Thor are about the same. And it's 100+ tons. He's nearly as strong as Superman. The only problem with the movie is that we haven't really seen him do any feats of strength in the movies. Flexing his power? Sure. Tossing around the Midgard Serpent? Not yet.
As far as Loki, he's a mage. One of the most powerful mages actually. So, that telepathic stuff you're talking about wasn't a power so much as it was a spell.
