Would hair transplant fall off over time? Would there be scars where the donor hairs are taken?

the transplanted hair will behave in the same way as your normal hair, it fall off and regrow again.

Yes there will be small scars on the donor area, but they will be hidden and covered with your hair.

I'm not able to give you very much information. You really need to find a person that has had a hair transplant. I've looked in my family medical guide and found the following information.

Hair transplants can be effective. Scalp plugs containing active follicles (hair cells) to be transplanted are taken from the back of the head, whuch is not affexted by male-pattern baldness. The trans-planted follicles continue to grow hair just as before, despite the new location. Sometimes the hair is moved and transplanted one hair at a time.The total cost can be as much as several thousand dollars and is rarely covered by health insurance.

I wish you the best of luck.
