Good.

I would like to switch over to using a uImage rather than the
cuboot.uImage. But I have not figured out whether it is the U-boot build
that converts the .dts to a .dtb or if the kernel build should do that. 

The dts is part of the kernel source, so its part of the kernel build 
procedure. You can either do this by hand or use the "make kilauea.dtb" 
target.

Also, I have not figured out whether the .dtb can remain part of the kernel
image, as it is with the cuboot kernel, or if the .dtb must be a separate
image in a different part of the rom.

When you use uImage, then U-Boot needs the dtb additionally to the kernel 
image. Those two images (and more) can be combined to a single image using 
the new U-Boot image format FIT (Flattened Image Tree) though.
