Answer 1

It is easy to get started in but a very very big program to become proficient in. It takes a long time to learn all the tricks functions.  

Answer 2

No is very easy, but you has to read to learn their commands parameters, to you can acomplish what you want, and help you to refresh you school math and geometry and sudenly all make sense.

But for begginers to get familiar they have cheap programs that teach the elemetarys like punch.com that have homedesign architectual series, they have all kind of sotfware for any aplication, but to me the best still autocad.
