Answer 1

Judging by the fourth line in your error block, you have

\usetikzlibrary{shape, geometric,arrows}

Neither shape nor geometric are names of libraries. There is a collection of libraries called shapes, and one of the libraries in that collection is shapes.geometric. Hence, you probably want either

\usetikzlibrary{shapes,arrows}

or

\usetikzlibrary{shapes.geometric,arrows}
