I had two flats on my new bike in rather short order. And railroad tracks were on my list of suspected factors though punctures were found also.
I got a kit for tire changes which I now carry in my fanny pack--thanks to the LBS guys who helped me put it together. I've read the how-to here at TE and watched some You Tube videos plus gotten some instruction from the LBS guys.
I want to be a "good" bike owner. I took my bike in for its' 100 mile check. I am hearing the message to air up tires all of the time--I was lazy on this at first. I read somewhere that you should before every ride check the tires and "bounce" the bike (drop it from a short distance) to note any rattles or loose parts. Anything else?
Chain cleaning? How often and how?
Anything else people feel compelled to add is okay, too.
