I'm using metal for the treaded bridges. Similar to the one you can see on Mel and Ann's site http://www.hurdygurdycrafters.com/index.asp?page=parts6.2 They sound fine. I like the adjustability of them as with the chanter bridge. I make up an adjustable height chanter bridge by using double bass adjustment screws. Just cut the bridge legs and drill holes to take the Bass screws. On my Jiri gurdy I even made adjustable dog bridges. I have an ebony slider which can screw in and out pushing the dog further away from the wheel if necessary. Makes for easy setup and fine tuning of all the string to wheel pressures. I haven't made two of the exact same gurdies and used wood (standard) versus metal (adjustable) bridges. So I can't really make a definitive comment on the deadening effect on sound using the metal. I like the sound I'm getting from my Jiri gurdy though.
I just use the standard brace setup. Easy to get the shaft lined up at drilling stage if the bushings are at the end block and at "brace two" (on my plan). It is critical to get the shaft at the correct angle and hence the wheel at the correct height above the sound board. I take your point about the pegbox attachment. I'll beef up the buttresses 'boat tails' and they get routed into slots in the peg head end block, as well as the peg head. I'll draw this in clearly.
