I've added those 2 questions
g99 to the bottom of the FAQ.
I'll keep editing to add answers, if I have the answers to add, that is
edit: Also, pertaining to professional developing: A lot of astro-photographers use hypered film or they push regular film to different speeds than it's rated for. ISO 3200 black and white kodak can be pushed to ISO 6400 or 9600, but that kind of handling of the film requires professional developers only, using special chemicals and developing processes. Pushing film that high increases it's grain size tremendously, so most pushing is something like ISO 100 to ISO 800, which is a very fine-grained film pushed to much higher speeds than it was meant for. It's also a very tricky process which is why I didnt mention it in the FAQ body.
