How do I know what size and thread Ti bolts to order, and wherefrom should I order?
Ti bolts will come in at helf the weight of steel. So expect to save 16g on 32g of steel bolts.
I went to a local long term hardware store and had them size the bolts. In the case of trial tech M6x20mm with a captured washer. While the Ritchey are M5. USA Ti on ebay has a great assortment of 6 bolt stem sets. Some say "for Ritchey this or that". Some sets just say "stem bolts". I've also ordered from some UK suppliers but they take a long time. The bolt length is measured from the tip to the under side of the head. That is, don't include the head in the length. It should not matter a lot if you get tapered head or not, but the tapered look better.
