4) You take the victory point tokens at the end of your turn. When the next player starts you will have already taken all the victory point tokens.
Exactly. The coins are really just place holders on the board so you remember what regions you just abandoned. That way you don't try to reconquer them (since gypsies must conquer regions other than the ones they just abandoned). Other players will NEVER have an opportunity to conquer those regions while your coins are still there since they go into your stash at the end of your turn.
