Congrats and enjoy every minute of it. After today, you will be a full citizen, except in TX...
If you have a digital scanner, just do a scan and will automatically be converted to a PDF file, and send yourself a copy of all those docs in an email. I would recommend using GMail, because it can accomodate large PDF files.

Moreover, save them on a flash drive, the one which you can take to a lockbox somewhere and wait till you an absolute need for them. If you decide to run for the Govenor of Idaho, you might need to prove that you came here legally, so having your own copy is better than Bill O' Reilly and Sean Hannity showing something completely fabricated...

I use this scanner at home for all my electronic filing needs. When you have important documents, filing them in a cabinet won't protect them from some vicious fire. Just a suggestion, it doesn't have to be this scanner, but there are comparables and maybe your job has one which you use at lunch time.
