Here is a publication from the Resilient Floor Covering Institute on the recommended practices for Removal of Resilient Floor Coverings

It covers both sheet goods and tile along with how best to remove the outer wear layer, backing, and adhesive without the use of harsh chemicals or strippers.
edit: They seem to keep changing their link. If they change it again I'm including this link to their site which has a good bit of information about resilient floor coverings in general.
