Instead of running - change things. Take it one step at a time. All these tools are valuable, but you can get by without some. Personally, I would start with Version Control, follow up with system/regression testing, then unit testing, continuous integration, and finally deployment process. I've never been in an environment with continuous integration. It hurts, and I'm trying to change that, but I've been picking my battles carefully and not pushed very hard on that one yet (challenges with integration into our version control platform). Don't run from the company, unless they're unable or unwilling to accept concrete proposals for changes. But be very cautious as the new guy. You don't want to continually annoy folks with your shiny new way of doing things. Be patient, research the reasons for each proposals, and try to work each one in over time.
