I'm trying to figure out how to actually get around to installing these into my brain in some sort of useful manner instead of just reading through them and then forgetting all about them.
So now I got a meta-question for each of the questions, "In which situations would I like this question to automatically pop into my head?"
Two approaches that come to mind are doing what CFAR calls offline habit training (finding a concrete trigger, tying it to an action using vivid associations, and repeating the trigger-association-action loop continuously for, say, 10 minutes) and installing them as social norms (ask all your friends to start asking each other these questions when relevant).

I just got back from the July CFAR workshop, where I was a guest instructor. One useful piece of rationality I started paying more attention to as a result of the workshop is the idea of useful questions to ask in various situations, particularly because I had been introduced to a new one:
"What skill am I actually training?"
This is a question that can be asked whenever you're practicing something, but more generally it can also be asked whenever you're doing something you do frequently, and it can help you notice when you're practicing a skill you weren't intending to train. Some examples of when to use this question:
Many of the lessons of the sequences can also be packaged as useful questions, like "what do I believe and why do I believe it?" and "what would I expect to see if this were true?"
I'd like to invite people to post other examples of useful questions in the comments, hopefully together with an explanation of why they're useful and some examples of when to use them. As usual, one useful question per comment for voting purposes.
