Eddy: [coming in through the screen door] "I smell breakfast!" Ed: [crashing through the screen door] "I smell friends."

By this, Ed means that he knows his friends are there: he "smells" friends.

Edd: [clearly upset at the broken screen door] "Ed, the screen door!" Ed: [ignorant] "Let's watch it!"

There, I think Ed's just suggesting they watch the screen door. The only semi-rational explanation that comes to my mind is that Ed heard the word "screen", associated that with TV, and thought they should watch it. That, or it's a weird Ed statement, but it probably has nothing to do with Friends the TV show, as he was referring to his friends with the statement "I smell friends."
