Debbie Wasserman-Schultz offers early opposition to Crist 2014

[Dereich]

So are we all pretty certain that both Charlie Crist and Alex Sink will seek the democratic nod for governor?

Both are all but assured to run. Rich is already in the race.

And does Florida have the same runoff law for election? Like, lets say that five candidates are on the ballot for the democratic primary, and either Crist or Sink win the initial primary election, but fall below 50% of the vote, would Sink and Crist go into a runoff?

Nope. We repealed it starting in 2002.

Okay, now in general election; what are the chances of one of those (Crist or Sink) winning the democratic nod but Bud Chiles running as an independent?

I don't think Chiles runs if Sink runs (he endorsed her last time), but he might if Crist runs and would prove a major pain (getting the 'he isn't a real Democrat' that make up ~20% of the FDP) but not a chance at the Governorship.

Does Scott win in a Crist-Scott-Chiles race?

It's certainly likely (what'd probably happen is like 2010 Senate, with Chiles as the Meek splitting the left), although not certain (the widespread anathema towards Scott, and Chiles doesn't have the D next to his name).

Is Chiles still a pretty popular former governor in Florida at least when it comes to Floridians picking their favorite governor, I realize Rick Scott might be their least favorite at least in recent history. But is Chiles still a popular name there like Reagan is in some parts of America at least through the nineties and into modern times?

Florida politics has changed a lot in the past few decades. Lawton Chiles was the last of the mostly (but not entirely) North Florida based rural and southern Democrats who dominated the state since forever. Chiles would probably be popular with Democrats still, but that would mostly be because he was the last governor with the (D) next to his name. Bob Graham better represents today's democrats, even though he was before Chiles. If Bud Chiles decided to run he couldn't just try to be a re-do of his father, the state is too different.
