You have already been trained in how to do this, so use what you already know and review what you are weak on in your PPL textbook.

Some gotchas new pilots frequently encounter are not knowing the FBO hours where they plan to buy fuel and getting grounded by that, not having adequate preparation in terms of weather, charts, airport info, etc. and depending too much on GPS for that, failing to check TFRs and other notams, and some of them lose situational awareness in terms of keeping track of where they are on a paper sectional. If it is a G1000 airplane you will have lots of data available to you, but don't be overly dependent on that. Use flight following services, get a briefing on DUATs before flying and read it, and carry some snacks. Oh, carry your camera too and shoot a few pictures.
