We discussed some of those questions in this thread:

Check it out.
My personal experience, and I took a long time fiddling with it:
I made a short list of 4 magical items, I made a list of books that was little more than those mentioned in L&L, I made a short list of stored vis prizes, and I made a long, whole list of tropaea. Each was defined by: amount, art and region. After the PCs had made their choices, I designed the other details of their tropaea.
With 24 tourney teams including 18 Normandy covenants, I chose to distribute around 220 prize tokens. I had around 40 pawns of stored vis, 150 pawns/year worth of tropaea, plus the L&L books and a couple of moderate/minor magical items.
Liege/Vassal charts are not complicated. Only the Tytali have more than one "tier" of vassals:
Fudarus - Exspectatio
Exspectatio - Atramentum Renatis
Confluensis - Dragon's Rest & Cunfin & 1 unnamed
Florum - Spider's Palace & Requies Eternae
Oleron - Nidi
Montverte - Atsingani
Independent: Eboris, Lapis Crudus (was formerly liege to at least 1 vassal)
I don't believe the Normandy map was made legally available as a PDF, unlike the Rhine map.
