I guess you are talking about the WEP protocol, not the new 802.11i. You can
find several papers describing WEP's flaws on the Internet. For example,

Yes. Or maybe you can read it from the wireless software on your first
computer...

It is the actual key (or actually a part of it, it is concatenated to an
initialization vector to form a per packet key). This is from which most of the
flaws originate.

?
When you connect to the wireless network, the access point authenticates the
network card. This requires that the same key is intalled to both the devices.
After the authentication the traffic is enrypted with the same key.

There are usually profiles for different networks in the wireless software. The
keys are stored in the profiles. When you switch to another network, the
corresponding profile is applied.

The same speed.

Because love falls for fools. ;)
