PCA Bubble Question

[Inyaface]

This is a somewhat interesting spot that I've had a fair amount of discution about.

There are 181 people left in the PCA and top 180 pay.
Folded to you in the CO with 27k chips. Blinds 1200/2400/300. Button is a tightish internet player with about 30k chips, sb is Shannon Shorr with about 70k and BB is a good vegas tourney pro with about 200k. What is your push range here?

2nd part. Your on the button with 30kish chips. Tightish internet player shoves the CO. What is your call range?
