I remember some weird Shadow-tech-hybrid destroyers that Earth built towards the end of the civil war, though.

The warlocks don't appear in the series IIRC, although I think Ivanova got appointed to command one when she transferred off B5 - don't recall if they said as much on screen though.
The Excalibur class were from the abortive spin-off series Crusade.

The Shadow hybrid destroyers were something else - Epsilon model of the Omega class I think...

And as for the EA buying Centauri jump engines ... I think that's mentioned in "In the beginning".
