Sonnie, it sounds like you need to prove to him that the whole Bible is inspired of God (2 Timothy 3:16, 17). It appears as though he believes some of it, but with the Bible it is all or nothing. It claims to be from God, and if it had teachings that were not true (as he seems to believe), then it would not be from God, and basically the whole thing would need to be discarded!

Here is one article that is along those lines:
If It's Just a Good Book, Then It's Not God's Book (by Eric Lyons)

If I were you, I would start amassing a pile of proof for the inspiration of the Bible, and I would take that approach with him. Topics such as Predictive Prophecy, Messianic Prophecy, Scientific Foreknowledge in the Bible, Historical Accuracy, Unity of the Bible, Archaeological Verification of the Bible, etc. would be enough to convince any objective person.

Eric Lyons has also written two books on alleged contradictions in the Bible, which I would recommend when dealing with skeptics: (The Anvil Rings, Vol. 1 and 2). I know you already have a lot of resources, such as links to Christian Evidences web sites, but if I can help in any other way let me know.
