Reddit reviews The North American High Tory Tradition

Just to point out, many Conservatives would disagree that Austrian Economics and Ayn Rand's Objectivism are even remotely Conservative (this is more related to the Libertarian branch of the Republican Party and is more correctly labeled "Libertarianism"). That said, I hope that you don't leave your studies with the notion that Milton Friedman and Ayn Rand necessarily represent Conservatism, because they most certainly don't (but to be fair, they are Right-Wing).

I like that Russel Kirk was on your reading list. Since you've read The Conservative Mind, I'm sure that you've read about Edmund Burke. I'd recommend Reflections on the Revolution in France. Another good book you may want to check out is The North American High Tory Tradition by Ron Dart. These works represent Traditional Conservativism, of which Russel Kirk was included.
