Very nice project, very similar to my Stumpy FSR, which is waiting for the chainstays coming back from BETD after bush replacement.
Shame about the cracked FOX
, they are quite hard to find second hand and from what i've gathered very hard to get spares for, Risse do new shocks but i have'nt checked the prices yet.
I have a BETD long travel conversion for the FSR, uses a FOX coil over shock and longer linkage plates, only trouble is it jacks the bike up too much (your frame looks the same size as mine), may be ok for a taller rider though.
Stickers should be fairly easy, contact member Gil-m on here, they wont be original stickers but he should be able to supply very good copys.
