ATs in SB preflop (+ some other questions)

[Obliky]

This is bad, right?

UTG is 60/11/1.6
Button is 60/0/0.8

About 100 hands on each villian.

Ultimate Bet 0.5/1 Hold'em (5 handed)

Preflop: Hero is SB with A[img]/images/graemlins/heart.gif[/img], T[img]/images/graemlins/heart.gif[/img].
UTG Raises, 1 fold, Button Calls, Hero folds...

Some Questions:

1, So should i be calling here?
2, What about if the villians are swopped? (I.e UTG is 60/0/0.8)

Back to the original hand (i.e. Villians are not swopped round)

3, Whats the worst broadway hand you CALL with here?
4, What the worst broadway hand you RAISE with here?
