Some great advice up on there and I would try and incorporate a bit of what everyone else has said. Spare pens and pencils is definately needed. You can usually find a whole bunch under the seat on your pre-flight where everyone else before you has dropped them.
In case you do get lost after trying all of your techniches don't be afraid to admit it and request help from ATC. You will not be a lesser pilot for doing so. The only other piece of advice I can give you is don't try and press on home
Have a small kit with you incase you have to divert and some cash or credit card and if the wx turns sour just land and wait it out. No one will think your a chicken for diverting and if you get through no one will treat you like a hero.
Enjoy
