Good advice above. The only thing I would add is that we have found it to be easier to hook the lines over the bollards (that are inset into the concrete wall) in the small locks if both bow and stern use a boat hook to help reach the wall with. I've seen a lot of boats do a great job of getting close to the wall but then they can't throw the line over the bollard and the current gets them. Pay strict attention to the lock masters and don't do anything until told to. When exiting the locks there is usually a lot of current so make sure the bowman let's the helm know when they are casting off. It sounds a lot more difficult than it is, you shouldn't have any trouble. Watch the RR bridge when you exit, it has a nasty habit of lowering while you are distracted in the locks.
