AsslaM o AlaikuM Bro,
I hope you will like My Suggestions:
1.) PAINT : There are 2 types of Stock Colors Those were ORIGINAL Paint colors.
a.) Candy Ruby Red Paint Code: R4C ~~~ Use the same paint for Mudguards if using Red Colour ~~~
b.) Candy Sapphire Blue Paint Code: PB3C ~~~ Use chrome with this Paint if Using Blue Colour ~~~
2.) I would suggest to find original CD200 Carb as its easily available in Pakistan with many people.
3.) Sorry Bro cannot guide about this Question as I do not belong to Multan or Bahawalpur but in Lahore Bilal Autos at Jail Road is the best mechanic.
4.) Yes keep it on Point System. Sazgaar can not touch the Genuine point system... But if you get CM250's CDI system then you may use it but my suggestion is to use only Point system.
5.) For brake system its upto your choice whether you want to install Disk Brake or Normal.
6.) That's also your choice, if you travel longer distances and drive in the evening or early morning, then its a good option.
7.) As you know these systems doesn't come as stock but if you like to have these readings additionally, its totally your choice. No issues.
I hope you would be quite satisfied with my suggestions, these are my personal Suggestions which I told you as per my experience. 
With Best Regards,
MuhammaD FarooQ.
