I stumbled upon On Trial at Barnes & Noble, not a place where you'd expect to find a handy book of tips for trial lawyers. The book's author, Henry Miller, wrote a column about trial advocacy for the New York Law Journal. On Trial is based on these columns, and is concise, witty, and very readable.
Here's a link to Amazon.com's listing of the book's table of contents. Some of the chapter titles: The Forty-Four Most Common Blunders of Jury Selection; Opening--the Twenty-Seven Steps; and Some Do's and Don'ts for Summation.
