Answer to Question 1

The astronaut would notice that initially s/he would first fall slowly because the gravitational pull would not be very large. The longer the astronaut fell, the closer s/he approached the center, the higher the gravitational pull, and the faster s/he would travel until you reached the event horizon.
An observer outside of the black hole would notice something differentthe effects of time dilation. They would see you fall more and more slowly as you approached the event horizon because time slows in a curved space-time.

Answer to Question 2

False
