Hi,
For early February, I would recommend not getting the Firenze Card as I think you don't want to try to jam as much as possible into just 72 hours and instead spread out what you see. Using Montecatini as a base, you can return to Florence on two non-consecutive days. Take day trips from there -- have you seen our article on the day trips you can take from Montecatini?

Are you certified as being partially disabled? If you are, you can use your ID to get free into many museums -- with priority access without needing to book any tickets ahead of time. An accompanying person can get into the museum with you for free as well.
February is a great month of the "low" season precisely because there are less people around in general -- but everything is still open. Locals enjoy the quieter months for sure ;-).
Carnival does take place in February if you do want to join in on festivities -- that's where you'll find a lot of people. You can check out what events are common in February here:

We'll update the page with precise dates in January as nothing is officially confirmed until we are much closer to the dates, but it gives you an idea of what takes place.
