How I setup my card:
read "man interfaces"
edited /etc/network/interfaces
added these lines (... represent tab):
iface eth1 inet static
...address 192.168.1.12
...netmask 255.255.255.0
...gateway 192.168.1.254
...pre-up /sbin/iwconfig eth1 mode managed key "whatever" essid basement
Then created my resolv.conf:
echo "nameserver 192.168.1.254" > /etc/resolv.conf

A lot easier then the GUI monstrosities that people think makes things so easy.
For Gentoo and Yoper they say they are very quick because they use compiler optimizations and kernel patches to make things quicker. For instance Debian compiles everything to work on a i386 machine. (could be i486) That's the default way of doing stuff. That way it works on all x86 machines no, problem. All of them from the ancient i386 machines, thru the weird cyrix and early AMD setups, on thru Pentium 4 and AMD64 platforms.
Buy allowing gcc to break backward compatability it allows you to use the improvements in the x86 platform that have developed since then. With Gentoo you use whatever you feel like and Yoper is compiled for "i686". It's a bit of a misnomer. First PC was the 8088 platform. That was all new and stuff, but it didn't work well with the earlier apps made for 8bit computers (I guess), so they came out with 8086. 8086 caught on well, so then they made 80286 computers that were faster and bigger. (80186 never existed I guess). After that they just added i to the front and dropped the 80 to signify intel's dominance and design.
Then came i386 and with the i486 the modern PC computer pretty much solidified. The 486 is mostly the same with all computers from then till the pentium4 and amd althon platform. The AMD64 was the first realy big step away from 486.
Of course the performance and efficiency of the platform increased when Intel released it's Pentium line of proccessors. So most people refer to pentium platform as "586" to signify the step. Then again intel increased the capabilities of x86 platform again dramaticly when they released the Pentium-Pro, and later the Pentium II setup.
Those added new instructions and such and are refered to as i686. Now people like to fall for marketing and beleive that the newer chips again offer significant increases and such and call them i786 and such, but they are smoking crack. There are other optimizations specificly to take advantage of the Pentium4 design and Althon design, trying to get the last ounce out of the newer chip designs. But mostly i686 will give you 98% of the improvement (which we are talking mostly single digit percentages or low teens in improvements over compiling for 486, except for specific cases), and compiling specificly for, say Pentium-4, may actually degrade performance.
So that's one thing that is good about Gentoo/Yoper. For Gentoo you have portage and all that. You compile your own OS on the fly for maximum flexibility, performance, and whatever else they think of. Mostly a waste of time, IMO, but you do get all the newest stuff first.
Yoper tries to be fast thru being clever with the setup and execution. It's like Ubunto, were it's designed to be a "Usable out of the box" desktop-centric type distro.
Stuff like Gentoo and Debian try to be a overall "everything you can possibly use it for" universal type distros. So with both you end up doing a lot of setup to get what you want.
