That is quite a project. Your list looks great, just wondering why you aren't considering a BNR 68hta? I use my car similar to how you intend to use yours, and love the 68hta.
I am starting to look into an engine build myself, so I too am trying to learn about internals as well. I have chosen 4032 pistons because they are quieter, use less oil, and are generally better for daily drivers. I will be going with CP's because I've heard that Mike from Infamous uses them for his builds, and that's enough to convince me.
I have an AEM intake that has done well, and is supposedly easy to tune.
I have the KillerB pickup and baffle, and so far they have done well in preventing oil starvation at the track, and haven't felt the need for the pan.
