As Šarūnas said, the two packages of interest on Debian are
linux-image-amd64 and linux-headers-amd64.  I even go so fars as to
apt-mark them as automatic:

    apt-get install -y linux-image-amd64 linux-headers-amd64
    apt-mark auto linux-image-amd64 linux-headers-amd64

And for the drivers, you may need to enable some repos and components
in /etc/apt/sources.list.  Specifically, non-free-firmware.  See
<https://wiki.debian.org/SourcesList>.
