`apt-get source <package>` will get you sources.

It is not ARM specific but Debian specific working on any architecture:
apt-get build-dep e2fsprogs
apt-get source -b e2fsprogs

There are several tools to build from sources, but there are
dependency loops which prevent that you can bootstrap Debian from
scratch, in other words, you can use dpkg-buildpackage, debuild,
svn-buildpackage, git-buildpackage, sbuild, etc... to compile a
package given you can fulfill its build dependencies, but you cannot
bootstrap Debian from sources due to dependency loops, work towards
this goal is very welcome.
