If your existing layout uses blocks, all you have to do to convert it to DCC have some DCC equiped locos, turn all the blocks, except any where you want to store DC locos, to "On" and connect the DCC system of your choice. If you have not already programed the DCC loco addresses on a seperate track, put them on the mainline one at a time and set their addresses. Once that's done, put them on the track, select a loco, and start operating. You can even put a DPDT toggle switch between the DC power supply and DCC system to switch back and forth when you want to operate the DC locos.
Personally, I use the NEC Power Cab because the add-on throttle is the same as the original, which cut down the learning curve for my grankids. The Zephyr is also a nice starter system, but the button layout on add-on throttles is not the same as the base unit.
