In general, SN260/EM260 were designed to work in connection to a host controller, therefore I would not recommend you to consider use of SN250/EM250 with Primer. SN260/EM260 are HW/SW compatible.
If you go to http://www.st.com/zigbee , you can find in the product selector section a reference to SPZB260 SN260 based module which fits with its size under the plastic shielding of Primer very well. It is also very simple to connect this module through J1 connector of Primer as there are all necessary signals available (SPI/Vcc/GND). In any case you can take any module based on SN260/EM260 and not just this one.
From the firmware point of view, it is enough to follow EZSP SPI commands described in the manual from ember http://www.ember.com/products_documentation.html . In my opinion a very nice start with Zigbee is through REva kit called SN260-2SK/RAIS based on tools from Raisonance where you will find beside two modules and two microcontroller boards also the necessary EZSP library (SPI API, in source codes) for STM32 communication with SN260 through SPI. I do not know if one can get the library from web. In case somebody knows, I would be interested to get the link.
