Preparing for 3.0

So tomorrow's the big day for 3.0. I'm totally unprepared, haven't been following along at all. I figured out what I need to know, though, and once I get the answers I'll summarize here. My big questions are:



What's the spec for max cat DPS?

What's the spec for strongest tanking?

What's a reasonable hybrid spec? (ideas here)

What's the new cat DPS cycle? (Karthis has my answer)

Did the bear threat generation cycle change?

New bear gear: tradeoff between armor, stamina, and dodge. (Emmerald not updated.)

New cat gear: tradeoff between agility, strength, attack power, crit, etc. (See Toskk.)

I think if I can answer all those questions reasonably well, I can join my guild's raid on Tuesday.
