Popular topics include stuff like TV shows, current events, sports games, movies, etc. Learn a number of facts about each of these things, at least enough to be able to ask and answer questions, and you should be OK. For talking to people past college age, books are a good topic as well (this refers to fiction books, not reference). A safe bet is the stuff people read in high school, especially politically charged books, such as "Farenheit 451", "1984", or "Brave New World".
You're right, but even more important than facts, IMHO, are personal anecdotes, interesting opinions, and things that make people laugh. For instance, if someone says IMHO (usually online, but its still relavent), you say something like "haha, I love 'IMHO'. You can get away with anything so long as you prefix it with that. You're a despicable person, IMHO. So and so is the antichrist, IMHO. etc".
