Hello Michael Wilson:
You can start by downloading the KE examples package (KEXX_DRIVERS_V1.2.1_DEVD) from the next product page link:
Freescale Freedom Development Platform for Ki|Freescale
The examples are for other IDEs (CodeWarrior, IAR, Keil) but you can take the code as base and copy it to a new project in KDS.
About the differences with Kinetis L, the startup code will be the same as both are ARM Cortex M0+, but with regards to the modules, a couple peripherals are practically the same (e.g. I2C/SPI), so you can reuse code with minor changes, but the rest are not (clock system, PORTs/GPIOs, Flash,...). So the migration is not transparent.
If you face any doubts or issues do not hesitate in letting us know.
Regards!
Jorge Gonzalez
