You don't say from which direction you will be arriving. If you are flying through Turkish airspace then you will be working "Erjan" on 126.7MHz and it will be up to you to liase with Nicosia before entering the Nicosia FIR. Erjan and Nicosia don't talk to each other, the full explanation is in the front of the Jeppesens.
Approaching from the west takes you over Cyprus and is straightforward. You can't approach from due south so you end up working Nicosia again and is straightforward. From the east you will work Damascus which is procedural. Beirut will "help" you on handover by giving you a more direct routing, cutting miles off your profile and leaving you high if you are not careful!
Normal landing on RW16 which is long, ILS equipped, and well lit. Departures are usually from RW21.
You will require overfly permits for many of the countries in the region and PPR is required for a landing in Beirut.
The Lebanese controllers are very good and will vector you onto finals with the minimum of interference or fuss.
Enjoy!
