You will probably be in Berkeley a little past 9am. If you are going to downtown Berkeley, take the dublin pleasanton train and transfer at Lake Merrit station to take the Richmond Train. Or, if you are traveling from Mon-Sat, you can transfer at any station before you cross the bay (past Daly city) to transfer to Richmond train. If you are going to Berkeley closer to rockridge, you need to still take dublin pleasanton train and transfer after Daly city to take the Pittsburg Bay Point train.
You would not want to go to the Dumbarton Bridge (which is in Palo Alto, very south), you would want to go to the San Mateo bridge (which is in San Mateo/Foster City) if you went south and that would add a lot of time to the trip. You would not gain a whole bunch of time as you would face the traffic heading north to the bay bridge maze through oakland at that time.
