As Notso says
Basically it is a normal take off, but airmanship says that you double check things - make sure the heading is the same as the QDM of the runway you want to use, tune the ILS (if available) and make sure it is centralised to ensure that you're on the centreline and not lined up on the edge lights, before lining up use TCAS mapping (prob not on -200) to check no aircraft about to land, count the number of centreline lights to confirm correct RVR.
When you are happy set power and look out, be very vigilant in maintaining the centreline track and as the speed increases the streaming effect of the centreline lights helps the tracking. Your mate should be heads in monitoring the instruments and speeds. Note: using reduced thrust can help in initial tracking of LOC signal as any deviation from it will happen slower, and reduced thrust will probably reduce likliehood of engine failure [not what you want in Cat 3 conditions].
As you achieve Vr, start the rotation at the normal rate (do not try to haul it off the ground) and transfer your view to inside the cockpit.
On some more modern aircraft (and some extinct ones) you may have a PVD (Para Visual Display) which is a rotating barbers pole which displays the LOC signal in a window on the coaming which helps confirm LOC tracking (or deviation from it and correction requierd) and allows lower RVR limits for take off.
