11-handed MTT advice sought

[beenben]

I'm planning on playing in a no-limit tournament with 11-handed tables, T4000 to start, blinds 25-50 to start, then double every half hour until it gets to 200-400, then the next level is 300-600, then 500-1000, 1k-2k, 2k-4k, 3-6, 5-10, 10-20 . . . Probably will be 132 seats and they'll seat alternates during the first level. Only the final table gets paid, with 75% to the top 4 spots.

What adjustments do I make? Play tighter pre-flop? What kind of a hand do you need at an 11-handed table to win, typically? How often per level do you think
you end up paying the blinds 11 handed? Once? 1.5 times?
