Hi Bob, I'm using the KE06128VLH4. It does not have a lot of requirements for getting it going. Only 2 sets of power pins for the core, 1 set for the analog supply. If you don't need CAN, you don't need a crystal. The internal clock source isn't stable enough for CAN. Bear in mind OpenSDA needs another Kinetis microcontroller providing the debugging interface; you would do well to just put the 10 pin header on your production board and use a separate debugger. The OpenSDA is convenient for the FRDM-KE06 board, though you can also populate the debug connector on it and use a separate debugger. I never had any problem using a P&E Multilink with the FRDM-KE06 board; I think the only thing I had to do was remove R35 to run the KE06 at 5 volts, which leaves the OpenSDA out of the picture.
One thing I found the hard way that I'll pass on; if you're using the SPI, the default SPI0_MISO pin (pin 13 on the 44-pin part) also happens to be the NMI pin after reset, and you would do well to put a pull down resistor on it to avoid any unpleasantness.
The SWD header only needs VDD, VSS, /reset, swd_dio, and swd_clk for debugging.
Edit: I forgot, the only glitch I had with using OpenSDA with the FRDM-KE06 involved updating the OpenSDA. Seems to me the default firmware that it comes with only provides the mass storage interface for loading firmware into the target processor; I had to load a different firmware image to get both the mass storage interface and the debug interface. It's not hard to do, but I did have to download something from Freescale to get the update.
