Ans: See the answer in point 2. Along with local accommodation address & contact number (if officer asks).
Make sure you complete the white form which will give you in side the flight, before landing. This form along with your passport has to be shown to the officer. The officer will return your passport along with your white form (only the stamp portion), which you need to submit at MoM on your visit for finger print and document verification.

Ans: Read the above.  You should carry all your original documents (educational and experiences letter) will be used at MoM. Good luck
