A compatibility matrix for different hardware/software versions is found here for the nRF51822 and here for the nRF51422

You do not need a bootloader to operate the chip, only if you want to be able to update your application/softdevice without physically connecting a programmer.

You can modify ROM and RAM settings in Keil with selecting Options for Target -> Target tab. These settings are specific for each softdevice. You can see settings required by opening any example code in the nRF51 made for a specific softdevice, and look at these settings in those examples.

I somehow had a S110 SoftDevice that would load but didn't work correctly, not allowing the demo to work. Starting from scratch, re-downloading all of the various components for the S10001 eval board, I can now see the Heart Rate demo from LightBlue. With this beach head I shold be able to make much faster progress. The questions above are all still valid and I would love to have them answered if possible.

I suspect the crux of my issues are due to trying to use these devices (any of the many nrf51822 instantiations) w/out the nRF6310 mobo and following the step-by-step instructions.

I also suspect, after spending time looking through the DevZone questions, that I'm not alone - meaning there are a number of folks attempting to develop directly to these devices. Each device seems similar, those with this radio, but it's not clear which SoftDevice, Program App, and Boot loader is desired/required.

Can I or should I use the same SoftDevice on a PCA1000 (dongle) as I would on the PCA10005 module?
Do I need a boot loader, or is that only if I want to do software updates?
Does Keil handle the memory mapping for these components, or do I need to understand and manually manage the segments?

I'm sure that many of these questions are answered in the docs, and will appear obvious once understood. But for the novice, there are certainly a lot of pieces to keep straight.
