Last questions before buying RO system

Thanks to advice here, I am buying an RO system from Purewater Products, out of Denton, TX. The Black and White unit has 4 stages: carbon block, membrane are the first 2. For the 3rd filter, I am getting a CR1 which is carbon and giardia filter.

1) I am thinking of getting a calcite cartridge for the 4th stage, which is supposed to add calcium and magnesium back into the water. This is supposed to be healthier? What will it do to the taste? Will any of these choices negatively affect the water pressure?

2) They offer air gap and non-air gap faucets. They say that they have a backflow tube which prevents cross-contamination, so that an air gap faucet is not strictly necessary. Any comments?
