(Blake Street is a little station on the north side of Birmingham)

When visting London via this route I usually get a day return to
Marylebone on Chiltern, with a zones 1-6 travelcard on the same
ticket. Would this cover me to catch the tube to padington, then the
train to Southall?, then the bus to Southall Broadway


Certainly will. Your current ticket (a day travelcard) already covers you
on all rail, tube and bus services throughout zones 1 to 6. Southall is in
zone 4.

The London Connections map has an explanation in the right hand column - you
should be able to pick one up at Marylebonel.
