Make a change to any of the settings in game and click the ok or apply button, this should generate some new folders within the unpacked game named '_appdata_'. Open that and then user.ltx with any text editor and search for 'cam inert'. Change the 0.whatever ( i forgot the original value ) to just 0 and this removes headbobbing.
Save the changes made and this should fix the issue.
As for point #2, check around the room for a med box, you'll find some pills in it. Facing the door out ( its locked ), wait for a soldier to be patrolling to your right, then use the painkiller meds and talk to him. Tell him you're sick, etc.
