Personally I would enable Naza mode in the Assistant right from the start. They say it's an advanced mode, but all you have to do is flip the s2 switch (the one on the top left) all the way up and it's exactly the same as flying in non-naza. In the meantime, you gain the benefit of home lock, which can be a life saver for bringing your phantom back when you get disoriented (and you will get disoriented - we all do). At the same time, make sure dynamic home point is NOT enabled, at least not to start.
Don't try to fly by FPV (first person view). Just use the video feed to help you frame shots and get yourself oriented from time to time.
Another tip to help you stay oriented is to turn your body in the same direction as your phantom. That way left and right for the phantom will be left and right for you. Sometimes this isn't possible if it means turning your back on your phantom, but otherwise, it's very helpful and could save you from a few crashes (a lot of tree crashes occur when someone tries to avoid a tree, but has gotten disoriented and ends up steering right into the tree).
UP is usually safe and throttling up (with your left stick) should be your first panic reaction in a pinch.
Do NOT crash your drone into the White House. They don't like that.
Do NOT run your batteries down to 0. Try to land before they drop below 40%.
Do NOT upgrade firmware right away when it's released. Wait for more experienced pilots to test it out and post back here if they find issues.
Flying backwards is a great way to fly fast with out the props ending up in your video - just be careful. Read the manual, but also read the guide linked to above.
If your experiencing problems with the tilt wheel for the camera, follow MoparBob's bobs instructions in the sticky to the letter, even if a step seems illogical or contradicts messages in the RC Assitant and/or Vision assistant (those are the 2 desktop apps for your vision plus).
There is more, but that's about all the advice that I can think of right now.
