Everday Life in Oman

I've been thinking about taking a trip to Oman, lately, but I have a few questions:
1. What are good topic of discussions, when first meeting someone and trying to make a good impression?
2.Is there anything I need to know about verbal and non-verbal communications?
3. Are public displays of affection, anger, or other emotions acceptable?
4. What should I know about the workplace environment (deadlines, dress, formality, etc.)?
6. When in this country, I would like to learn more about the cultures and people, what activities would you recommend?
7. Who are this country's national heroes?
8. What's the family life like?
9. Describe work in this country.
10. What types of sports and recreation activities are important there?
11. What healthcare is available to the people there?
12. Describe the educational system.
13. What are the important holidays in this country? (& explain the purpose of each, please)
14. What arts and literature are important in this country?
15. What meals do they have and how are they usually served?

If you could answer any of these questions, it would be greatly appreciated. Thanks in advance.
