Florida allows you take a crib sheet into the polls. I published a full-length voting guide a few days ago, but here's the summary version:
Senator: Meek, or Crist if you think it will stop Rubio. At this writing I'm leaning Crist, but I change my mind five times a day.
Congress: FL-25, vote for Joe Garcia, FL-22 vote for Ron Klein. In other districts your vote for a Democrat is a vote against the Tea Party and its fellow travelers.
Governor: Alex Sink. Stopping Rick Scott is important.
Attorney General: Dan Gelber. The GOP's Pam Bondi is a particularly horrible candidate.
[UPDATE: Florida CFO: Loranne Ausley. Any vote against Jeff Atwater is a good vote. Plus Ausley, currently the chair of Florida Healthy Kids Corporation, likely would do a fine job.]
Commissioner of Agriculture & Consumer Services: Scott Maddox.
State Representative District 111: Christina Albright.
(I don't live in Miami-Dade County Commission District 8, but if I did I would vote for Eugene Flinn; he's great and the other candidate is awful, just awful.
Non-partisan Judicial Retention Elections: Vote to retain the Justices and Judges.
State Constitutional Amendments (pay attention here, these matter)
Amendment One: NO.
Amendment Two: No recommendation, although I'll vote no.
Amendment Four: Yes.
Amendment Five: YES!
Amendment Six: YES!
Amendment Eight: NO!
Non-binding Resolution on Balancing the Federal Budget: No.
Miami-Dade Home Rule Charter Amendment: No.
