The order of details should be statement, support, elaboration. As long as a fact is supporting an earlier mentioned statement, it should stay in the story. If you say the vote was 4-3, the fact Smith, Jones, Schwartz and Hemp voted one way and Michaels, Sounder and Caucus voted another is a supporting fact, and should be kept in the story. By the way, this is a chance to make sure the numbers match. If the vote is 4-3, make sure you have seven names in the story.
Quotes add color to a story, and sometimes help clarify issues.
If you haven't been told to cut, leave them in. However, make sure they are properly set up and do not confuse the reader. Most quotes need to be introduced by a paraphrase setting the stage. Always look for one. If there are multiple positions being advanced in the story, make sure everyone gets a turn at being quoted.
