Why fly back? Have you found yourself a future employer who will accept a family permit as evidence of the right to work? If not, be aware that as a US citizen you currently do not need a visa to enter the UK as the spouse of an EU national working in the UK. Having entered on that basis, you can then try to use the 'EEA Regulations stamp' you will receive as evidence of a right to work, and apply for a residence card to give employers and landlords statutory defences against penalties for employing or letting to illegal immigrants.
The driving while disqualified might conceivably cause a problem. Are you sure you don't need to mention the disqualification itself? There could be an argument that if allowed into the UK you might be a danger to the public once behind the wheel.
There are reports that they will reconsider your status, so you need to keep the evidence of status with you and be able to contact your husband on arrival. You US passport will be good enough to board a flight to the UK.
It takes more than 7 days to apply - an application is not complete until the biometrics have been taken. You can apply for the return of your passport after applying, but it takes many days, even weeks, which is why Tiems recommended the European passport return service.
