Yup! I worked as a technician doing this kind of stuff.
There are small chances that the wall jacks aren't terminated, but I'd say it's pretty likely they're done properly seeing as the ends in the patch panel are terminated.
It's interesting that there are some extra, I'd be curious where they go. You'll be able to ascertain them one-by-one quite easily though. I'd just plug them into a switch in the patch panel one at a time and then go to my house-jacks to test. A little tedious, but then you could label them yourself, if you wanted to.
