2014 Leaf S Lease

Thinking of getting the 2014 Leaf S on a lease.
My questions are:

Does the $7500 IRS credit come off the purchase at lease end?
Will I still get the $2500 CA cash rebate even though it is a lease?
Or does the dealer get that…If they do get the $2500 can I apply it to the down?
The optional Quick Charge, How much is it? And can I add it to the lease vehicle? 30 min charge? is that from 0% battery?

Many many thanks for your attention and anticipated responses…
