I think you should get the Chilton AND Haynes. I have them both and there's stuff in the Chilton book that's not in the Haynes and vice versa. For example my Chilton book has complete wiring and vacuum diagrams including fault code listings and troubleshooting for the ECU, the Haynes doesn't. But the Haynes has some simple tests (with an Ohm meter) for the distributor and other components that the Chilton book lacks. I'd like to find even more manuals if I could, you can never have too much information about your vehicle!
