Years ago I managed several rental car facilities in FL. The only explination I can perhaps give for the difference in the amonts between the first and second letter is that once the vehicle was looked at by professional it was determined that the vehicle was not repairable and was a total loss. This could be the case if there was damage to the frame that wouldn't be noticable until they attempted to repair the car or if they found more internal damge that would be unsafe of too costly too repair (ie more than the actual value of the car). Many times these cars are leased and owned by a leasing company who may make the determination in the car is in a condition to be repaired or if it is considered a total loss.
As for loss of use this could go either way. I know many rental companies are a franchise meaning that the local owner many own all the vehicles in their fleet and may have a limited number of vehicles, if they can prove that this particular vehicle would have been out on rent had it not been damage they may be able to collect for loss of use, however if they had a cars sitting idle during this time it will be very hard to prove that they actually lost any revenue due to the damage.
As for the rental agreement most are pretty binding and legal regardless of weather the conditions and policies are on the actual agreement that you sign or reffer you to the policies on their folder.
As a side note be very thankfull that you did not hit another vehicle as Amex only covers the rental vehicle not any liability. State laws very and in FL the rental car company only carries the state minimun of 10/20/10. This means that should you hit another person and cause damage or injury above the rental companies basic coverage you may be liable for the difference.
As many have stated I would recomend that you contact a lawyer to help you sort through this.
