Thanks Enidigm. I'd also suggest the book "Rehabilitating Lochner" which is a smaller book that tackles a very controversial Supreme Court case from a conservative jurisprudence view.
@IkeVandergraaf if you are willing to watch or listen instead of read there are also a ton of (free) videos that cover conservative thought.
http://econlib.org/ is a great resource for classical liberal vein of conservative economic thought. They have a podcast EconTalk that hosts a wide range of economic opinion makers (economists, journalist, etc.) that is another great resource.
