Since system configuration is done and SSH AcceptEnv problem is solved, I think it's a good time to update/upgrade Raspbian. It doesn't matter if you installed the latest version of Raspbian. Even if you do, you should still update/upgrade before going any further. Actually if you skip this step, camera module may not work. It's pretty easy as doing `sudo apt-get update` and `sudo apt-get upgrade`. Why not do it?
Now that basic configuration and update/upgrade is done, we can install VNC server/client to emulate Raspberry Pi's screen on your PC.
