1. Yes, I thought the move felt like a true ensemble piece. No one character dominated in terms of screen time so much that it was noticeable. One of the keys to that, I think, was that every scene served a purpose in the film, nothing was extraneous and no moment was wasted. So it never felt like "Iron Man & Friends," "Nick Fury and his Mighty Pokemon," etc.
2. Yep! Tony was lying on the ground after Hulk leapt up and rescued him. With that armor on, Cap couldn't do much for him. Cap, Thor and Hulk hovered over Stark for a moment, at a loss. Then Hulk roared like a mofo and shocked Tony awake. The audience roared, too.

gave Tony a file on Cap, Hulk and Thor. When Tony put it on his monitors there
may have been a photo of Peggy. I'll have to ask my bro if he saw it.
4. As a Cap fan, I was completely satisfied at the way his leadership skills were showcased during the battle. Steve Rogers was portrayed as a natural leader and strategist who could assess a situation on the fly and plan tactics perfectly. He was an inspirational leader to the Avengers and the police and military on the ground.
