In doubles pickleball, what information should the server call out before each serve?

The server should call out their team's score, the opposing team's score, and the server number.

In doubles, which player serves first for their team at the start of each game?

The player in the right service court serves first.

The two players switch places and the same server serves again.

I can describe the basic rules and scoring of pickleball.

1
In pickleball, a game is typically played to 11 points, and a team must win by 2 points.
2
In doubles pickleball, the server announces the score by stating their team's score, then the opposing team's score, and finally the server number.
3
In singles pickleball, the server announces the score by stating their score, then the opposing team's score; the server number is not needed.
