Debian – Install programs without an internet connection on Debian

So I've been battling with my debian install lately, it doesn't have the firmware for either eth0 or wan0 NIC's. However, I got a firmware.zip file that I need to extract to /lib/firmware. The problem is, since I have no connection from the computer, I can't just apt-get what I want.

Here's my question, I don't know a huge amount about the natural dependencies of Linux (Debian specifically), so I need to know a way to get them installed without internet. I can't even unzip this firmware file I have to get internet because as far as I can tell there is no default unzipping program. If I were to download the package and transfer it over on my USB drive, then it wouldn't run, because it needs libbz2-1.0, libc0.1, libc6, libc6.1, and libgcc1. It also suggests a program called zip. libc6 requires libc-bin and recommends libc6-i686, and suggests debconf.libc0.1.

Without being able to unzip anything who knows if I'll even be able to install these things. Do you guys know if there's just a very basic package that will install all these standard packages for me?

I'm going to put some of the errors I'm getting now even though I think that I installed the drivers.

This is where I get really confused:

ifconfig wlan1 192.168.10.111
b43-phy0 ERROR: Firmware file "B43/ucode5.fw" not found
b43-phy0 ERROR: Firmware file "B43-open/ucode5.fw" not found
b43-phy0 ERROR: You must go to blah blah blah and get the firmware
SIOCSIFFLAGSS: No such file or directory

So despite the fact that my dmesg says that the 43xx driver is loaded, ifconfig says it's not. What do I do at this point? I'll post a bit more data in one minute.

So I guess I didn't run firmware-b43-installer_4.150.10.5-4_all.deb. I just did it by typing this:

dpkg -i firmware-b43-installer_4.150.10.5-4_all.deb
(Reading database ... 14006 files and directories currently installed.)
Preparing to replace firmware-b43-installer 4.150.10.5-4 (using firmware-b43-installer_4.150.10.5-4_all.deb) ...
Unpacking replacement firmware-b43-installer ...
Setting up firmware-b43-installer (4.150.10.5-4) ...
...

However at this point it tries to access a mirror (http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2). Holy crap is there any way possible to just get files that don't require an internet connection?
