How to setup multi-monitor display with laptop and PC using docking station

I have a three monitor setup that is running off my desktop PC. I also have a laptop that sits on my desk and I'd like to setup my laptop so that I can display what's on my laptop on my far right-side monitor using a docking station or port replicator, but still have the other two monitors running off my desktop PC. I also have a wireless keyboard and mouse that runs on my desktop PC. I'd like to be able to switch between using the wireless keyboard and mouse on the desktop PC to the laptop as needed. I keep my email and chat open on my laptop and do most of my work my desktop PC. I'd monitor my email and chat off my laptop on my far right side monitor and as I need to respond, I could switch my keyboard and mouse to work off the laptop and then when finished go back to working on my desktop PC. (see embedded image). What  would I need to configure this type of setup? Thanks.

Rather than using hardware consider Remote Desktop onto the laptop displaying it on your third screen.
