Questions:
1. Am I right in understanding that points are awarded per team, and when they're awarded it doesn't matter what the score of the victory was — 2:1 or 3:0? And are points awarded separately for each match? That is, the maximum one team in a group can score is ten thirty points?

Correct — if there had been 5 players per team, the volleyball system would have been applied. If you know what I mean. But there is one nuance. It's an additional tiebreaker in case of equal points. I didn't calculate it, but a situation may be possible where, if points are equal, the number of wins is taken into account. And if two players of one team win their games, the third — in terms of point counting — might not need to play, but in terms of counting the number of wins it's to his advantage to play and win the 3rd game of the matchup. So if he simply didn't play because his team already beat the other team, he could let his team down in a situation where the number of wins is being counted — again, if such situations are possible.

2. The rules state that each round is given two weeks. A total of ten games must be played. That means the group stage will last five months. Is that correct?

Yes, about four and a half months. If the players play faster, of course, everything can be shortened. Besides, the situation in the groups may become a foregone conclusion under certain circumstances — for example, a round or two before the end of the group stage.
