Paragon's BB shell heatsink/purgue is perfectly made at a very fair price. For headset and seat tube you can make your own or make someone made them for you (I had a super great job made by this Vsalon member Sebaudet ,thanks Seb!)
To me, it's always useful to watch what the experienced people are doing so to learn their process (wich is usually based in long years of experience), there're no shortcuts, sure you'll be able to find your own way on the process, but they're the best living lessons to start with (mixed with your own workbench hours). Watching any of the workshop process pictures from Tig masters like Tyler, Drew, Rody, Sean, Kris, Mike, etc will help you understand what goes where and why, and see what you might need to do the best possible work.
I could never thank them enough for all the information they openly share for anyone to see how does hell's oven get fired. No microwaves here
Cheers
