Table in progress. Corrections, comments are welcome.
Aside from the above table,
the following is the link for THE best site for the races for the 2012 Republican presidential nominating convention: http://www.thegreenpapers.com/P12/R-DSVE.phtml
The Florida and Virginia primaries (January 31 and March 6, and 50 delegates and 46 delegates, respectively) will be pivotal. Florida will be a winner-take-all state.
Florida polls hours: they are open 7 AM to 7 PM (yet, the West Florida Panhandle votes has a later deadline, as the 7 PM Central Time closing time is 8 PM Eastern Time.
(Source: http://seattletimes.nwsource.com/html/politics/2017380004_campaignslog31.html)
Virginia winner-take-all at the district level; WTA at state level if a candidate gets a majority. These Virginia rules will be moot, since Mitt Romney and Ron Paul were the only ones that qualified for the ballot, one of the two will get a majority, of course.
So, in essence, Virginia is throwing the nomination to Romney, with its ballot qualification rules.

The following states had their allotted delegate counts reduced by 50 percent for moving their primary election dates earlier: New Hampshire, South Carolina, Florida, Arizona, Michigan.
1,128 delegates are needed for the Republican nomination; 2,255 delegates are available.

The site, "The Green Papers: Presidential Primaries 2012: Republican Delegate Selection and Voter Eligibility", gives a wide range of important details: not just election date, but also indications for primary or caucus, winner take all or proportional, number of delegates:
