Welcome!
You might also take a look at
www.technokats.org (no, it's not a shameless plug)
Specifically under "file archives" and "Links". There are design documents, i.e. transmissions, posted that can be very helpful.
You should also take a look at the "white papers" section of ChiefDelphi forums, like Rich suggested. There's tons of information in there spanning a wide variety of topics.
When in doubt ask - take some time to search these forums and other sites and you'll be in good shape.
