Rime of the ancient Marin[er]

So, a little progress (Poste Italiane is very slow). Thus far:

1. Marin Team frame
   
2. Mosso alu fork (26", +/- 750g, v-brake + disc) as I couldn't face buying a third Kona P2
   
3. Deore XT crankset (FC-M751)
   
4. Flite Titanium saddle
   
5. 26" NOS wheelset (DT Hügi / Shimano XT hubs, Bontrager Mustang rims)
   
6. Blackspire Snaggletooth chainring, 34t [plus a Raceface nw 36t]
   
7. Silver 27.2mm Shogun seatpost
   
   

Not sure on the following:

1. Bottom bracket (Shimano ES51 68mm octalink) any other options? Any idea on axle length?
   
2. Handlebar: Renthal, Raceface, Ritchey, Spank - very difficult to find in silver with a decent amount of rise
   
3. Stem: probably going for a Hope or similar with shortish reach, colour undecided
   
4. Tyres: God knows
   
5. Brakes: discs or v-brake? Could put a disc in the front, but know nothing about them. Avid, TRP, Magura, Shimano?
   
6. Rear cog: probably a Gusset or Surly single speed adaptor kit, 13t
