As far as gaming performance, the HD4000 is not bad but you will have to give details on what performance you are looking for. It can be considered "good" for games like LoL, WoW etc but terrible for Battlefield 3. But in general, it's capable if you are fine with generally lower settings on Games from this year and last year, and higher up for older games or console ports.

The 13" MBP can yield a few more frame rates thanks to a higher clocked CPU and GPU, but GPU intensive games won't notice a big difference between the MBP and MBA's HD 4000.

A 2011 Air SSD won't fit in a 2012 Macbook Air, but you can put it in this enclosure from OWC and use it as a USB 3 external drive:
