Nice camera!
In short, use one laptop, there's no need to separate them.
The wsg is self guiding so you're going to want to use the same bit of software for guiding and imaging I would imagine. That's how I do it with CCDSoft and my SBIG STT8300 with self guiding filter wheel.
I control my EQ6 with EQMOD and Stellarium and plate solve with AstroTortilla. The camera is connected to the guide port on the mount via a cable though depending on the software you use you might be able to send the guiding corrections through EQMOD instead.
Good luck
