walkthrough: Rails 2.0 startup process

I haven’t found a complete big-picture walkthrough for the Rails startup process when I looked for one recently.

There are some really useful resources about this but they are for Rails 1.2 and each of them only covers certain parts of the process. Thus, I’ve taken some notes while reading to the Rails code and compiled the following guide from them.

By now I guess I've gotten a little snow-blind ... any feedback, corrections or additions would be highly appreciated!

Thanks!
