I failed to mention that the lander can's monopropellant tank is cut off because RCS has to be on for the second stage to control itself during launch, and I didn't want to deplete the lander of monopropellant so quickly. When you undock from the lander to head down to the Mun/Minmus, you may wish to turn on the monopropellant tank again by right clicking the lander can and clicking on the little "no" symbol next to the monopropellant so that it turn to a green arrow.
Also, you may notice that the craft does have a launch escape system. To activate it, use the Abort action group. Otherwise, it will stage off after the first stage is separated.
One more thing that I failed to mention is that I used TweakScale (or TweakUI, whatever you call it) to get the fuel tank for the CSM just right. You will need to install TweakScale or this craft will not load.
Also, more screenshots:
