I can answer one piece definitively for you...

Select * is extremely inefficient as all the
fieldnames must be queried from the DB and returned
before the data starts to come over. With a named
SELECT, that entire process is skipped.

Also, Chris, if in your research you happen to come
across an answer for my previous TheList question
about the relative efficiency of FSO vs. DB Lookups,
let me know, willya!
