I think FoMoCo has you covered on the bulbs. For the flashing battery light I'd suggest you first make sure all the wiring between the alternator and battery is clean and tight, not just the power wires but also the ground cable from battery to chassis/engine block. Make sure the connection to the fuse/relay distribution block is also clean and tight. If that doesn't fix the light, then you might need to get out the multimeter and test the charging system under varying conditions, particularly when starting. On more than one occasion I've experienced those quick testers stating a battery or alternator is good when in actual use it proves out otherwise.
