1) No; PS Touch is not free (but once you do buy it, it can certainly work with CC). I suspect this may be because of the way the mobile marketplace works. (PS Touch is both on Google Play and iTunes, two completely different marketplaces separate from Adobe.) I could picture a rebate arrangement on Adobe's part in the future, though.
2) Don't know the answer to this question, sorry.
Thank you Warunicorn!
