Handy Things the IRS Can Do For You

By calling one toll-free number:
800–829–1040, you can get answers to your tax questions, order free publications and order transcripts of information you entered on previous tax returns.  All of these services are free. 

With regard to publications, may I suggest Publication 17, both for its utility in answering tax questions and helping you fall asleep.

The automated system for getting transcripts will ask you for your address, so I'm not sure how it will react if you want things sent to a new address because you've moved.  In any case, though, the phone system is quite efficient, and you can order multiple transcripts with one phone call.
