This is the default situation, you first have to create the hashes
database.

Be sure to understand that rkhunter hashes test is not meant to replace
more powerful tools, like eg. integrit.

Yes, I think so, though not recently tested.
1.3.2 has a replacement tool for hashupd.sh embedded in the core
package.

Not needed

I supply ***unofficial*** backports of rkhunter package in my personal
repository at http://packages.kirya.net
I use these backports on my servers.

This might be the best solution for you is you want to benefit from all
the improvements of the newer releases.

Etch is the current stable distribution, hence cannot be updated (except
for major issues, eg. security fixes).
