The approach controllers at Kabul are all pretty sharp. They are all ex-pats, and do an incredible job providing vectors away from both terrain and other traffic. If you are a little worried about being vectored in above the glideslope, just request to descend in the hold at WEBRO, down to 13600ft (I think it is off the top of my head), and that will avoid having to make any dramatic rates of decent to get onto the vertical profile.
As the guys have said, be prepared for very bad jamming on VHF, and also watch out for the choppers that will do parallel approaches onto the taxiways on either side of you, sometimes in bad vis. I've had plenty RA's on the ILS just before the TCAS goes to TA only mode, and it can be very unnerving in bad weather.
The other thing to factor in. DELAYS... both for arrivals and departures. When Karzai or one of his Cronies decide to go flying, the airport comes to a complete standstill, with little or no warning. You can expect departure delays when the VIZ drops below 5000m, up to an hour at the holding point (regardless of if you are an Airliner, or King Air). So if you have the luxury of extra fuel, and your company won't string you up by the nuts for taking extra fuel, then take the extra fuel.
I have been flying a medium cat turbo prop in and out of there for almost 2 years, so much of what I've said may have no relevance to your operation into Kabul, but I thought I'd share it nonetheless. Safe flying!
