Yes, if that phase has not resolved yet: replace the chosen card with the upgraded version, and receive its bonus instead of the normal one. To upgrade, choose an upgraded card and replace the corresponding card in your hand (or the faceup chosen card if you chose that phase this round) (p. 3).

One player takes the Milestone tile, and each other player who achieved it takes a 3 VP token. At game end, a Milestone or 3 VP token scores 3 VP (p. 3).

Normally, most earns 5 VP and second-most earns 2 VP. A tie for most gives each tied player 4 VP and no award for second; a tie for second gives each tied player 1 VP (p. 3).
