Answer 1

Yesterday, we released the version 0.11; which supports the generation of the changelogs containing only your changes. The changes are applied automatically on the database. No need to drop your database now.

Try it. http://jhipster.github.io/2014/02/19/jhipster-release-0.11.0.html

I have not used jhipster at all, but normal liquibase usage is to not keep dropping the database but rather append new changeSets to your db-changelog.xml file. For example, if you originally had a changeSet and need to add a column you append an changeSet. That way you don't lose data and liquibase keeps track of which changes have been ran against your databases.
