Now, before committing suicide having important documents on my home dir,
what steps should I try to recover also part of the tar file?

Since gzip uses the same compression as zip, you might try Info-Zip's zipfix
program ON A COPY of the tarball (www.info-zip.org).  As far as I can tell
it isn't packaged for Debian.
summer@mail:~$ dpkg --status zip
Package: zip
Status: install ok installed
Priority: optional
Section: utils
Installed-Size: 184
Maintainer: Santiago Vila <sanvila@debian.org>
Version: 2.30-5
Replaces: zip-crypt (<= 2.30-2)
Depends: libc6 (>= 2.1.2)
Recommends: unzip
Conflicts: zip-crypt (<= 2.30-2)
Description: Archiver for .zip files
This is InfoZIP's zip program. It produces files that are fully
compatible with the popular PKZIP program; however, the command line
options are not identical. In other words, the end result is the same,
but the methods differ. :-)
This version supports encryption.

Not that I think it's got any chance of working, but I'd be vicariously pleased to hear otherwise.
