Be careful not to use attribution as a throw in spot for unneeded information. Either find a different home for the information, preferably a new paragraph, or leave it out. The best approach is straightforward.
"It's hot," John Doe said. Do not write: "I think it's a lot like my pinkie," said Majerle, who broke the digit on his shooting hand a week ago, sat out one game, and experienced enough.."
Each quote needs attribution; each quote needs only one attribution. Use said, not sighed, exclaimed, gasped, etc.
Put attribution at the end of the first complete sentence.
Set quotes off by themselves in paragraphs.
If consecutive paragraph's of quotes have different speakers, put the attribution at the front of the second/third/fourth speakers. Use Murray said: or Said Murray: Commas may be used instead of semicolons.
