How can I install software or packages without internet (offline)?

I am about to format my computer and install Ubuntu. This particular computer is the local server that provides internet to all machines in our network. I will be installing Ubuntu 12.04 Server Edition. However, for my internet to work I need a particular package, which is not included in the regular list of packages that are included in the installation. This is the Madwimax package.

After I install Ubuntu, what is the proper way to install Madwimax, without some manual install (i.e. using apt-get, but without having internet)? Currently I still have internet so I can go and download certain packages, but I'm just not sure what and how.

I need to reset my password. I have followed these steps:

How do I reset a lost administrative password?

However, then I go to "root" or "netroot" recovery options, it tells me:

Give root password for maintenance (or type Control-D to continue)

Clearly, I do not know the root password. If I type CTRL+D, I return to the list of options. From this page I read:

Under chapter 'The Other Way':

4. Highlight the line that begins kernel and press 'e' to edit`

But in the grub configuration file I have no line that starts with kernel. Only:

setparams 'Ubuntu...'
recordfail
set gxfpayload...
insmod part_msdos
insmod ext2
set root=...
search --no-floppy...
linux /boot/vmlinuz-2.6.38...
initrd /boot/initrd.img-2.6....

Those are all lines in my GRUB. Which line should I edit? Or is there another way to reset my password?
