They're 17mm Allen heads.  The two at the bottom are drain plugs, and the one 
level with the driveshafts is the filler.  You need a 17mm driver similar to 
Snap-On's SAM17A.  You'll also need to apply a fair amount of torque to break 
it free if it's not been moved since the car was built.  The socket is _very_ 
shallow as it is - it's a good idea to clean it out _thoroughly_ before 
inserting the driver - and support the driver so it doesn't twist in the 
socket. Easily stripped.
 
Differential oil comes in bottles with long nozzles.  You remove the filler 
plug, insert the end of the nozzle through the filler hole, and squeeze.  You 
know it's full when oil starts to run down your sleeve.
