You apply for the FLR AFTER you get married.
If/when you get the FLR, they'll issue you with a biometrics ID card.
This card will have an end date on it ... eg 28 April 2014.
You then apply for the ILR within 28 days (not before) of this end date ie 1 April 2014
Cost ? ,.... I think the FLR is about £850
The ILR is around £930
... but I'm sure someone will correct me.
