Wireless communication between two arduinos

Hello,
I am new to development on arduino boards and would like some guidance for my project.

I basically need to generate 3 PWM signals and transfer them over a wireless network to another arduino using zigbee. I also require a keyboard interface on one of the arduino kit.

I'd like to know which arduino kits would suffice my needs.
Required:
2 arduino kits with keyboard interface and zigbee module.
