Attempting to add packages from "testing" into a machine tracking Debian's "stable" branch is a common beginner's error, and an excellent way to screw up your system. The packaging system isn't designed to support that sort of frankensteining of two tracks with such an extremely wide versioning gulf between them, and to attempt it is to solve the wrong problem.
People determined to stubbornly cling to Debian's "stable" track should use, instead, the backports.org collections — or leave their machines alone — or do the sensible thing and put the entire machine onto the "testing" track rather than frankensteining it. Or use Ubuntu.
If anyone advised you to do otherwise, that person was very badly informed — and was giving out really bad advice.
My own server and desktop systems tend to track either testing with optional access to unstable-track packages, or follow unstable.

The notion that "releases" are somehow vital is an error commonly put forward by people not acquainted with gradually-moving tracks such as Debian-testing and Debian-unstable. Please see: "Releases Unimportant" on http://linuxmafia.com/kb/Debian/ .
Moreover, the people stating it are invariably ignorant of Debian's point-releases for the stable branch, e.g.:
[snip table, recreated and expanded below]
These have been the standardised Official Debian installation CD image releases, as announced on the debian-cd and debian-release mailing lists and sold by CD vendors.
(Surprised? Well, that's because you posted misinformation for lack of acquaintance with the subject.)
Not that it's significant, but I'll point out that those releases have been (generally) significantly more frequent than Red Hat's, whose dates I track here: "RH Releases" on http://linuxmafia.com/kb/RedHat

Because early Debian Project Leader Bruce Perens worked at Pixar Studios, makers of the animated film "Toy Story", Debian branches adopted the convention of bearing nicknames taken from characters in that movie.
Track name "stable" within the Debian packaging system also resolves to whatever is the release branch at any given time. It is implemented as a symlink within the package mirror network, that is relinked to each new release on the day the Debian release manager declares it production-ready.

Debian Pending Releases, Point Releases, and Non-Release Branches
Active Debian development occurs in a continuously rolling (non-release) track called "unstable", which is permanently assigned Toy Story branch name "Sid" (Sidney Phillips), the name of the film's neighbour boy who destroyed and tortured toys. Any new or updated package unloaded by a Debian developer becomes immediately available in master package mirror site directory tree "sid" (symlink "unstable") as compiled and packaged by the project's automated build hosts.
"sid" also houses CPU architectures not officially supported but planned to be integrated later.
Since 2000, a separate continuously rolling track called "testing", implemented as another symlink in the master package mirror tree has existed that has two roles: Most of the time, it is programmatically defined by a nightly maintenance script on the master package mirror that adds to its package collection any newly uploaded packages in "unstable" if any only if they pass a set of automated quality-testing criteria. (Thus, it functions as a quarantining script.) However, when the Debian Release Manager is preparing for a new "stable" release, he/she manually intervenes with some of that script's operations to enforce desired contents, e.g., holding libc at a desired release level. Around that time, the "testing" contents are given a symlinked version number in the master package mirror's directory structure, as testing branch "lenny" will soon receive the Debian5.0 symlink (a/o this writing in April 2008). When he/she considers a "testing" collection fully ready to become the new "stable" release, the "stable" symlink gets repointed to that set of files, and a new rolling "testing" branch is started, gaining that symlink.
Version Released Name Note 5.0 (pending) Lenny Current "testing" branch, which will be assigned 5.0 but officially isn't yet (a/o 18 Apr 2008). Will be the next "stable" branch, estimated Sept. 2008 time-frame. Will drop 32-bit SPARC. Will include nearly full UTF-8 charset support. "Lenny" was the pair of wind-up walking binoculars.
Between full releases, each "stable" relese gets re-released up to seven (going by past cycles) additioanl times, to merge in security updates, kernel/driver improvements to support newer hardware, and critical bug-fixes. Thus, the current "stable" release of Etch at this writing (18 April 2008) is actually Debian4.0r3, the fourth Etch release. Each point release is Official Debian, and has its own set of stable packages, CD images, and DVD images -- for each officially supported architecture.
Because all 1000+ Debian developers are expected to normally keep their systems syncrhonised frequently to the "unstable" branch, it's deemed bad to upload broken packages to there, even briefly. So, the "expermental" package collection exists as an upload targets for developers' "highly experimental software where there's a good chance that the software could break your system, or software that's just too unstable even for the unstable distribution (but there is a reason to package it nevertheless".
