Regarding disclaimers and warranties and things of that nature, we don't give out specific legal advice, sorry about that; it's the responsibility of every author to make sure they've got these things right.
Our recommendation with issues like this is to look for precedents in similar books, or to search online resources like the Alliance of Independent Authors for help:
Alliance of Independent Authors
Reaching out to our global community of self-published authors on the Leanpub Authors Forum is also a good idea:
