Guys I'm sorry for the extremely late reply. I had an unfortunate incident (death) in my family, and was down and out because of that.
I would like everyone on this forum to know that they have been extremely helpful in letting me know all the details of the trip. I remember that Punjab highways were a pleasure to drive on but as soon as I touched Saqidabad, its like a different world in Sindh, the roads are the worst, and Moro, oh don't even ask about moro.
Anyways I got alot of help through this forum and alot of prompt replies which helped me alot. The highway code book was also of great help as the police in Sindh kept asking me for it and at times just to test them of what they'll do if I say I don't have it, they said they will give me a chalaan of Rs.3000 and upon asking them for the chalaan receipt, they said, fine give us Rs.2500 and you can go now or else we'll have to call out officer who will take time and until he does, we will not be able to let you leave. So I showed them the book, they got shocked that I was playing them, started my car and was on THE WAY 
Oh and the fuel cost was unbelievable, it cost me 9000 all the way down from Islamabad to Karachi and the total journey time was 18hrs, Toll to toll.
So this is to all who helped, thank you for all the help, couldn't have done it without the out of the way help from you guys. Cheers to All.
