One thing I'll add to all the advice is, use EDDiscovery and Captain's log to keep track of your trip. Make a note of the interesting stuff you find and you should have a pretty good memento once you're all done, plus a list of systems you may want to revisit one day (say, when landing on ELW's comes you may want to revisit that pretty ringed one, as an example).
Only other suggestion would be to use Iridium Wing when coming back - they will keep you and your data safe.
EDD is an excellent tool and one which I only started using on DWE. Not only does it help to keep track of your journey it also (in my opinion) helps mitigate extreme Space Madness.
