Re the OEB - After the first bleed failure you really need to reduce pack flow on the remaining bleed or it will overheat faster than you can reach for your QRH and then find the OEB, especially in climb.
Make the LO/ECON Pack flow selection a memory recall action with no delay even before actioning the OEB.
