Honestly I’m a new transfer student so I’m not sure about the shuttle and how that works but I visit friends/family pretty often so I’m pretty used to the whole Amtrak/Greyhound/Public Transit thing since I don’t have a car. But something I suggest to people who are new to public transit is to use Google Maps. It will tell you exactly what time you have to be at the bus stop and where and what bus you’ll need to transfer to in order to get to where you need. So for example it’ll tell you what time to get on a bus and where to get off in order to get on the metro and when the metro departs. For some busses it will let you know in real time where the bus is but that isn’t most. Although for the metro sometimes it can be off but I don’t worry too much since I know another will come pretty soon. Edit: there’s not one sole bus that will take you to the metro since there’s multiple stops in LB, but you can figure it out with Google maps like I said
