You don't need to remove anything but the belt. Swinging out the lock carrier would make it easier, but not worth the time on this job (unless you have big gorilla arms). It's fairly easy. You put a wrench on the tensioner, turn it and slip a drill bit, punch or allen wrench in the locking hole. Getting the top of the belt off is easy. The bottom pulleys are a bit trickier (especially the alternator) as there are lines running in front of them. Getting the belt on is much easier than removing it, so if you get frustrated just cut it. Oh, another thing. If you don't have a manual and your memory is bad, draw a picture of the routing!
BTW- Don't be too concerned about small cracks on the old belt where it runs across a pulley "upside-down". They are normal. If there are any areas where ribs are missing or any fraying on the edge, change the belt.
