I'm inclined to agree with Maverick Philosoper Bill Vallicella that the following essays are as good as any for the purpose:
Michael Novak, Lonely Atheists of the Global Village.
Alvin Plantinga, The Dawkins Confusion: Naturalism Ad Absurdum.
Alvin Plantinga, Darwin, Mind, and Meaning
Read and absorb those, and you'll have invested all the time you need in acquiring your arsenal.
