Debian Backports fully supports secure-apt (that is, you add a line to your /etc/apt/sources.list and apt-get/aptitude will warn you if there is a problem with signatures). As to the original question, I would suggest installing wheezy NOW on your test server. You will probably want some time to configure and test the server before deploying it in production. Wheezy will be going stable soon (a couple of months is the last estimate I heard) so you should be fine there. This is the whole point of the testing distribution, AFAIUI. You run 'stable' on your production server and 'testing' on your development server. You do your development and testing of the newer version on your development server and when that distribution is released, you're in a good position to update the production server with minimal impact (because you already know how the changes will impact your userbase). The production server then remains with a relatively fixed set of software. Apologies if this sounds like teaching you to suck eggs.
