so.. why did the black rook not take the knight on the first move?

cause checkmate is then faster a fact

after knight c8, black can move pawn to f6 and he will prolong the game

i thought the solution was interesting but I really dont understand the logic behind some of first moves.  Is the solution really absolutely the best moves or are some of these puzzles more demonstrative/interesting than tactical?

The logic behind 1.Nc8 is that white cuts off the black rook from defending d8 threatening checkmate.  The logic behind 1..., Nd5 is to prevent white from having a direct shot at d8 as 1..., Rxc8 loses to 2.Qd8+, Rxd8, 3.Rxd8#.  The logic behind 2.Qb4+, is that black cannot play 2..., Nxb4 because of 3.Rd8#.  The logic here is not readily visible, but the moves played are the best for black unless you consider massive material loss as better than losing to checkmate.  Try looking through some of the earlier posts with diagrams to see how that is.

there is no way to avoid this mate and every move is forced.  if you deviate in any way it will cause a faster checkmate. yes

Not necessarily.  Black could play something like f6 as his first move and avoid immediate mate, but would lose material as a result.
