Not a BF expert, but I'd say eliminate the one that makes life most convenient for you. Your body should regulate when it needs and doesn't need to produce milk. About whether or not to pump, that will depend on whether or not you feel engorged and need to relieve some pressure, etc. If you are sore you might want to pump or manually express a little to avoid any blockages, but it shouldn't take too long for them to get used to not feeding at that time.
