I do not think GSLV is ready, and won't be ready any time sooner although they are testing it in December. Also, I think GSLV should achieve workhorse capability like PSLV before it can be tasked with major workloads. I think NASA is helping with the payloads on MOM. I would be curious to know which ones are contributions by NASA though [1]. Also, the landing gear is designed with the help of ROSCOSMOS [2]. Some more detailed information in these links [3, 4, 5].
