An efficient firmware level developer has years of software and
ideally also hardware education (autodidact, or otherwise) as well as
development experience. That can't really be packaged in a video that
can just be clicked on in a web browser.

There is however a lot of documentation available online, and of
course the source code can be used to learn a lot!

There are several presentations about coreboot available online, but
they are all somewhat introductory and overviewy, because it is
difficult to go into all details in only 40 minutes.

The better way to start is typically from the other end - learn all
you can about lowlevel PC programming in general, and then focus on
coreboot. coreboot isn't a great place to learn everything you need.
It can certainly be done, but it will take a very long time.

If you have already opened your laptop several times to do some
hacking, and you figured out how to do it yourself, I think it could
be really interesting to work on coreboot. You would learn about
every single pin (there are a thousand or so) on the major chips in
your laptop, you would get a soldering iron if you don't already have
one and you would learn how to solder surface mount components on the
laptop mainboard. You could also help yourself by learning about
electronics, voltages and current, in order to turn your laptop
(meant for users) into an embedded systems development board (good
for firmware level development). This might mostly consist of
mechanical (i.e. physical) hacks, to be able to run the system
without the case, but that can be very tricky.

That's impossible to say without knowing exactly what the tool did.

I would say that if your system still starts and runs, and you notice
no problems while running the system, then your BIOS is still OK.
