I’d answer the question differently, as is my wont.
Don’t try to keep a checklist of “things not to talk about”. That’s a sure way to kill conversations. Leave your options open to talk about anything, and let your date bring up what he/she will. No subject should be taboo. (That’s a good way to avoid Date #2 if you want to, because you’ll seem like a wet blanket.) Anything can be discussed that the two parties think is relevant or acceptable. If you find something unacceptable, then it’s okay to mention that, too. (Try not to do it often. For example, you’ll note that @Dutchess married the guy whose conversation she found “totally gross”.)
No, the bigger thing is “What should we talk about?” In a date with a new person where you’re trying to get to know each other, sometimes the problem is trying to come up with topics to discuss.
So make your own mental checklist of things that you’d like to know about your new date (or things that you’d like him to know about you) and figure out how to steer the conversation in those directions. It’s always helpful to see something in your current environment (with the other person) and make an observation about that, in a way that ties it to your experience.
For example: You’re on the sidewalk heading to the restaurant and you see a really broken-down old car parked at the curb. You both see it. You can make the observation (if it applies) that your family once owned a car like that, and you’re glad that you still don’t (or wish that you still did). Or maybe you see a hot new car and relate that to the car your date is driving (positively, if you can). That way you’re developing common points of reference; seeing things together and starting from those common reference points to develop conversations about things that you can both see and relate to. Doing that helps to understand each other when the conversation gets more into “invisible” things, feelings, etc.
When all else fails, because even with animated and interested people sometimes an awkward lull can fall on a conversation, tell him (it won’t really be a fib, because I did read this and now I’m referring you to it), “I once read an article about ‘conversation’ that said intelligent people should be able to discuss anything from babies to helicopter maintenance. So… what are your thoughts on helicopter maintenance?” It has worked several times to reanimate conversations that I’ve had.
