I talked with people at work and here are our observations:

1. The vial he injected had the familiar string of numbers on it
2. the number entered into the computer had the same numbers
3. I believe the button that Walt said not to push is the one Jack almost did
4. The island is the quarantine-not the shaft (as others have said here)
5. The guy that Jack's wife/slash fiance hit in her accident (he died) had the same last name as Shannon
6. the graffti in the tunnel had 108 in it which equals the sum of the string of numbers
