To attempt to give you some direct answers-
1- Not great. Most ME carriers only employ experienced pilots (EK, 4000hrs + jet time as an example). You might check out the likes of Jazerah or Air Arabia, but my feeling is you'll need some time elsewhere first. I assume you are of an Arab nationality? That won't hurt.
2- No. They employ Pilots, not Wannabe pilots. Achieve their minimum requirements before applying.
3- As an indicator of your education and ability to study,yes. But as an actual qualification, no.
Out of interest, why have you chosen a UK based school? Training is much cheaper in Australia, and the GA work scene there is pretty good.
