Are merchant services being worked on for GoldCoin Microguy? ie payment processing?
This is a most excellent question.

Much like Bitcoin, the development team's responsibility is in the building of the core foundation with 1.) the Goldcoin client and 2.) the Android app. It will ultimately be the overall community that takes this core and expands upon it into such things such as pools, exchanges, and service offerings such as merchant POS systems.
The great thing about the payment processing part of the equation is that existing Bitcoin merchants can be adapted quite easily to accept Goldcoin payment. So this part of the growth will be driven more by customer demand than by systems development which is mostly a straight forward process of integration.
