Where do I find a PGN?

When a game ends, most chess sites offer to download or copy the move list as a PGN.

What is a FEN?

It is a one-line record of a single position: where the pieces stand, whose turn it is and which special moves are still allowed. You can copy it from a board editor.

Why does the evaluation keep changing?

The longer the search runs, the more replies it checks. A fast result can shift a little when you look again.
