Definitely buy the Gliem because it is a killer value and nothing else has what it does. Buy your PPL study book whether it be Jepp, Rod, or some other book. You'll have to have th FAR/AIM for you oral to reference if needed and the PTS just tells you what to expect during the oral/checkride. And get the aviation weather book, aviation weather services, and flying handbook which the FAA publishes. These are great even after you pass. I still use them when I can't remember a METAR or FA word.
