A limited but incredibly useful list of actions sorted by the order they
first fire is on the Codex Action Reference:

For diagnostic info you're probably best-off putting it in the footer then
using jQuery to show it at the top. Better yet, why not investigate the
Debug Bar plugin's API for adding panels and use that. I haven't tried it
but it's probably pretty simple and there are other plugins that use it:
