I missed this post

Quill stem - a tubular steel stem will be stiffer, if that's what you want. The Nitto will work fine though and the DA AX stem (I believe that was it) was super nice (and probably pretty rare).

BioPace - you have a reason for this? Usually it reduces your ability to spin. Some folks used a round big ring and a BP small ring, but even then, people sort of phased them out.

Front der - BP was designed to work with Shimano's normal front derailleurs. Mount it high enough to barely clear the big ring when it's "tallest" and you should be set. I'd use a inner chain watcher type thing if you use BP.

Chain - you can use any 9 or 10s chain. I used to use XT chains for a long time, check mtb chains (Shimano). They'll be quiet and strong.

Shoes - I don't know if you have straps on those shoes but you'll need them for clipless pedals if you don't. I jury rigged straps on my non-strapped shoes.
