"The question then is; how does the atmosphere that is mostly carbon dioxide, affect the evaporation or sublimation of water and the temperature of the planets surface?"
On earth at "normal range" of air pressure, CO2 is either a gas or solid. If Earth's air pressure was about 5 times greater then CO2 at certain temperatures would have liquid phase- btw, and given that the Earth's ocean has has greater pressure, you could liquid CO2 in our oceans. If you were to pump CO2 gas in the ocean at a depths greater than than about 150', then you would have Liquid CO2 in same way that you can have Liquid CO2 in a fire extinguisher.
Water at lower pressure boils lower temperature- if you cooking food with water- say boiling macaroni, and one is living on a mountain, you will need to boil it longer because it boils at lower temperature.
"Another question is; at what height above the Earth does the Earth’s atmospheric pressure match the pressure at the surface of Mars?"
About 100,000'
