What should I be aware of in buying second-hand sinks and toilets?

I applaud your effort at frugality and environmentalism. The "throwaway" mindset peeves me to no end. Many folks change out fixtures just to change the look or size, and there are plenty of good units ...

Outside hose bibb with very fine thread?

What you see there is a vacuum breaker spigot with its pants down. You'll need to try and procure the parts or just replace the whole works. More on that

Can Teflon thread tape be reused?

I agree with Ed Beal that you should replace it, but if you're in a pinch you certainly can reuse PTFE tape, assuming you recover enough of it and it's not totally shredded. Carefully unwrap it and ...
