Airport Express & Netgear routers....Again!

Question

I've just bought an airport express expecting to be able to link it to my existing wireless network with a netgear DG834G2 router , guess I was naive to think it would be easy!
I've read the thread by MacAddict39 and being a bit green I'm not sure how to go about some of it so if someone could guide me and answer my questions it would be fantastic.
1. Connect the AirPort Express to your wired network; you do not need wireless to configure it, as it'll grab a DHCP lease itself off a LAN, assuming it's not setup for wifi yet. If you already screwed yours up royally, just push and hold the reset button -- wait and try this step again. It'll then use your LAN as it would out of box.
Do I use an ethernet cable and do I plug it into the router?what's DHCP?
2. Use the AirPort Admin Program, not the Setup Assistant. You can then enter the IP manually it gets from DHCP, or just scan the network to find it with AirPort Admin (insure you first install the latest version kids).
Where do I find the IP?being new from the box shouldn't the AX have the latest version?
3. When setting up your AirPort Express, enter your SSID by hand, and don't worry if it doesn't see it. Is the SSID NETGEAR?
4. When you enter the 128 bit WEP key, don't use the passphrase, use the key (hex code) generated/shown in the NETGEAR config screen. When you enter this code into the AirPort Admin app, preceed this code with the '$' character, as this tells it that you are entering a hex code, not the string literal thats used to generate the key. Yes, in both password fields add that '$' character -- both times. Where abouts do I find the WEP hex code?
5. Apply the changes (I set the AirPort Express to join my wireless network, since it's using wireless as a client). It'll take about 30 seconds to reboot and voila. You owe me a beer.
It'll be worth a beer after all this buggering about!
Thank you for any help you can provide......Cheers Phil

You should configure your AX to connect to the Netgear router in client mode.
What is client mode?

You can do this wirelessly from your Mac.
If you have tried to configure before then you may need to reset the AX first.

Do I use an ethernet cable and do I plug it into the
router?
Yes that is what the instructions mean.
what's DHCP?
Simply this a process by which a router assigns IP addresses to clients on the network automatically.
Each client (computer or AX) needs their own individual IP address.
Where do I find the IP?
Using the Airport Admin Utility, therefore you need to be able to connect to it to know the IP address.
Your Netgear router may have a list of connected devices and therefore you can get the IP address that way.
being new from the box
shouldn't the AX have the latest version?
Sometimes yes, sometimes no.
. When setting up your AirPort Express, enter your
SSID by hand, and don't worry if it doesn't see it.
Is the SSID NETGEAR?
If your Netgear's wireless network name is NETGEAR, which it probably will be if you haven't changed the SSID from the default configuration.
Where abouts do I find the WEP
hex code?
First did you configure the Netgear router to use WEP?
From the configuration page of the Netgear router which will be accessed from a web browser, check the Netgear manual for details on how to do this.
