Answer 1

Well, I can solve half your mystery. For the first flight, the second row lists codeshares:

2  PG 133 Y 14JUL 1 BKKUSM DK1  1100 1205  14JUL  E  0 319 S                  
   010 AB 4378 /AY 6277 /BA 7965 /EY 7662 /KL 3732 /QF 3494 /QR 

Since flight PG133 is codeshared as QR4012, the /QR 40 2 bit is almost certainly a typo/copypaste mistake for /QR 4012, and you'll note that the second flight lists /QR 4007 as you'd expect.

No clue about 908 17 though. I would have guessed it might be a partial ticket number, but that should start with the issuing carrier, and 908 is Voyageur Airways, an obscure Canadian charter outfit. (Bangkok Airways is 829.)
