Suggestion for a day visit to Amritsar

I’m planning to visit Amritsar on Feb 10th for a day. Landing at 6:45 am and returning at 10 pm the same day. I want to see Golden temple and Wagha border mainly. It’s been on my bucket list for years. Planning to have breakfast and lunch at lungar (eternally grateful 🙏). Can someone help answer below questions? Thanks in advance. 1. What time does Wagha border allow visitors to get in? How long does the event last? 2. Are there any paid tickets for best viewing experience? If not, how soon should I reach there to get the best seats? 3. What are the best places to have dinner around apart from lungar? 4. What are the other places to see in between? 5. Anything I should be aware of considering I’ll be visiting on Monday? (Closures, limited hours, etc) 6. How is the Uber service to commute between airport and these attractions?
