With what atmosphere/water? We can't even keep our current planet habitable.

  That's what terraforming is - it creates/modifies/brings what is needed for an atmosphere and water and everything else. We can't keep our current planet habitable because of current forcings that are not present on Mars, like varying governments, greed, incentives, etc. Plus, trying to live sustainably on Mars is likely to teach us more about how to live sustainably here. It's quite a logical fallacy to suggest we shouldn't/can't try to make Mars human habitably simply because we're struggling with Earth right now. Doing both things at the same time would be related to each other and help each other.

    brings what is needed for an atmosphere and water and everything else. Bring from where? governments, greed, incentives, etc. You really think those forces will disappear on Mars? You only need to look back a few 100 years for an example of this exact scenario playing out (the wild west in America).

  The most likely candidate for the atmosphere is melted co2. Mara would have liquid oceans if the co2 ice caps were melted away. From there, a biosphere would need to be introduced for oxygen production. The main limiter on earth based animal life would be a lack of buffer gas such as nitrogen, and the excessive co2 concentrations.
