It all depends. It should be a straight forward swap of the bridge. If the setup is pretty good right now, and you feel confident in your ability to adjust the bridge, go for it. Just remember that, unless you have a strobe tuner, you will not be able to do an adequate job on intonation.
You could, if you wanted, swap the bridge, and then bring it to a good repair person for the setup. This may help to offset the cost of the work. Of course, if you get the old bridge off and the new one does not line up perfectly, then take it to a repair person. Take great care when you are removing the old bridge not to damage the finish (at least, if you care), and also be cautious with the ground wire which should be attached to the bridge.
