Thanks to the Avengers Movie (saw it today), here are some feats for the characters:
Loki - no-sells assault-rifle fire, no-sells Captain America's punches, blind catches an arrow out of the air, engages a not-really-trying-too-hard-Thor in prolonged HtH and takes a number of hits without dying.
IM - Displays LOTS of new weapons, really good durability, electricity absorption, storage and redirection via repulsors, pretty high strength - high enough to knock Thor about (though not to hurt him in any real way).
Thor - Adds at least a dozen feats for deflecting energy beams with /swings/ of his hammer - so it might be good for BT status. Adds massive lightning capabilities - potent enough to mess up a huge number enemies including some VERY tough ones for a prolonged interval. Shows the strength to catch Hulk's fist, to knock IM and Hulk around, to crack Tony's armor and to crack a cage designed to hold the Hulk. Durability to tank numerous hits from IM, Hulk and Loki without showing any damage (Hulk briefly stunned him with a couple of hits). Does a huge amount of fighting with the only wound he takes during the whole film. Shows excellent fighting ability (no shock there - he already had that).
Cap - Has probably class 2-5 strength, somewhat (but not that far) sub-Spiderman agility tricks, fantastic fighting ability, never really has anything like a real BT feat.
Hawkeye - pretty much like comics Barton - somewhere around peak human HtH - but not close to Cap, superhuman accuracy with a bow, makes pretty awesome trick-shots.
Black Widow - About like in IM2, though she adds seductress/manipulator/interrogator to her list of feats.
Hulk - Moves at above peak-human speed, shows the durability to take shots from Thor without staying down, probably shows not far from class-100 strength in one feat, shows a sense of humor, shows reanimating breath. Other stuff would spoil it. :-)
Finally, like for any Marvel film, stay into the credits. You get to see the bad guy for Avengers 2. :-)
