Please tell me about the re-entry permit.

I am planning to return to Japan for a year and a half after getting a re-entry permit, but
should I hire a lawyer to get it ？
I am very worried because I have never gotten it yet.
How many months before my return should I apply ？
I heard that I can leave the U.S.
after my fingerprints are done, but where do I pick up my re-entry permit
in Japan ？ on line? 965>
Please tell me about your experience.
Thank you very much.
