Ubuntu Networking :: Banging Head Against Wall- How To Setup Wifi On An Inspiron 9300?

I've had 8.04 for almost a year & a half now, but the one thing that seems to confuse me after getting the rest of ubuntu is how to get wifi working. Before you say "read XXX FAQ, wiki, page", etc, I've read so many and despite understanding every normal thing about ubuntu, and all the customization I have, I haven't seen a single, up-to-date guide for making sense of wifi.

Here's what I know:

My wireless card is Network controller: Intel Corporation PRO/Wireless 2915ABG Network Connection (rev 05), supported in linux only by using a windows driver, ipw2200, which I do have running and installed somehow.

Code:
shogun@Valhalla:~$ sudo lsmod | grep ipw2200
[sudo] password for shogun:
ipw2200 146248 0
ieee80211 35528 1 ipw2200

I also realized I needed ndiswrapper, so I installed that. Beyond this, I'll just admit it- I'm very confused. I have always had a working connection over ethernet cable plugged in, but I really need wireless lately, and found an old Netgear WGR614v7 G band wireless rounter in my basement, hooked it up, and have a wired connection from it right now.

So how do I set-up/get my wireless working with all this thus far? How do I set up the router's network through Ubuntu as well, so I can create a named network to connect to? I'm reading every guide I can, and am just coming up more confused.
