Get the lightweight/better quality "dove tail type" spoiler from Shahid Autos in Markaz F-10 Islamabad. For new LCD check out any place in Saddar, as for the scratches if they are not too deep, try out the SONAX windscreen polish which you can get at a better price from Autoline in Saddar, Rawalpindi.
55W generic Chinese HIDs with warranty are available with Shahid Autos (F-10 Isb) for 7000/- BUT If you want somewhat branded ones with quality and performance, then PM me.
