Calling pushes in the end game

[11t]

I was just wondering what people had to say about calling requirements during the bubble/itm period of a tournament. I mean of course you should be looking for a premium hand but if you have a bigger stack should you loosen up your calling requirments so that a) people are less willing to push against you and b) you have the chips necessary to gamble even when you aren't getting the greatest odds. I have two hands here I was wondering what people have to say about them and what they would do.

PokerStars No-Limit Hold'em Tourney, Big Blind is t600 (3 handed) converter

BB (t4815)
Button (t4450)
Hero (t4235)

Preflop: Hero is SB with 5[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/spade.gif[/img].

Now here is a little murkier situation and I was wondering what people would do here as well

PokerStars No-Limit Hold'em Tourney, Big Blind is t400 (4 handed) converter

UTG (t2730)
Button (t3075)
SB (t1730)
Hero (t5965)

Preflop: Hero is BB with T[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/club.gif[/img].
<font color="#666666">2 folds</font>, <font color="#CC3333">SB raises to t1705</font>,

Are these both auto folds? I'll post what I did later if anybody cares.
