As I was saying before, I wanted to install spindles on the lower half of the porch, mainly for safety, but also so it would match the porch on the front of the house - the one I'll be updating soon so stay tuned.
The stops I installed for the screened panels also served as great nailers for the spindles. That was one of the reasons I decided to go with the stops in the first place. Putting the spindles in place was pretty much what you would expect, although one nice trick I learned was to cut two pieces of wood the same length as the space between the spindles to serve as spacers while installing them. This ended up being a valuable time saver and the spindles went in rather quickly.
