Salam sahirzzz,
It's nice to see yur interest in Economics.
Your query.....
Papere I
Well I'll suggest yu to go through K.K Dewett(Modern Economic Theory) for better understanding of theory, and P.A.Samuelson(Economics) for good study of application.and for the part of 'Islamic Economic systems', books by Maulana Taqi Usmani are the best.
Paper II
Paper II of Economics covers 'economics of Pakistan ( development since 1947). For this paper there's a good book by 'Syed Kamal Hyder & M.Syed Nasir' ( Economics of Pakistan). Along with this book yu may consult encarta and wikipedia.
i think
its enough for today.
Regards
Qurat
