Exhaustive scholarly responses to the books published by the so-called "Jesus Seminar" are:
Michael Wilkins & J.P. Moreland, eds.
Jesus Under Fire: Modern Scholarship Reinvents the Historical Jesus
Zondervan Publishing House, 256p, $16.99
Boyd, Gregory A.
Cynic, Sage, or Son of God?
SP Pubns, 1995, $15.99, ISBN 1-56476-448-6
If you don't have the patience for long and scholarly books, Gregory A Boyd has also written a small book, a condensed version of the above in easy popular language without all the footnotes and technical jargon. Maybe that is the best intro for seeing laid out the arguments against the Jesus Seminar as well as the positive evidence for the conservative Christian position.
