Very nice collection!
Regarding the wings, as far as I know they go like this:
Bronze: 5 jumps, this is the common one issued to conscripts of the LJK.
Silver: 35 jumps, now this takes some time.
Gold: 150 jumps, not many of these around.
You're just missing the new subdued patch worn with the M05 uniform, I think I saw one for sale on ebay.de some time ago...
