Is it generally a good idea to disengage the overdrive (which is on by
default) in my 2004 Focus when doing city driving (lots of stopping/
starting, hills, etc.). It seems to make sense but then I wonder
whether it is good for the transmission to be regularly disengaging
the overdrive like that. Or is the preferred practice to simply leave
it in overdrive with the rare exception of climbing/descending major
hills and the like.

The simple answer is, NO. Top gear, OD, does not engage until around 35 MPH
or so. If you car that had a three speed tranny would you drive around in
second gear?

It seems that when I disengage the OD even below 35 MPH, the car kicks
into a lower gear. Why would this be if the car isn't technically in
OD until around 35 MPH?
Thanks,

Try reading your owners manual, then operate the vehicle as suggested
therein, WBMA

If you find the car hunts back and forth into top gear, then yes disable the
OD- it is recommended for Foci, and Mondeo's in the UK where habitual
hunting back and forth kills the 'box, as the torque loading shreds the 3rd
gear clutch pack.
