Going off of the model you provided for your machine, this is what the output ports on your motherboard should look like:
"D" is the VGA out for the integrated ATI® Radeon™ HD 3200 (based off of the specs found here: http://www.gateway.com/product_spec....ecid=529668104
). "G" is going to be your integrated NIC- the ethernet port that allows you to connect to networks (i.e. - the internet). "H", "I", "J", and "L" are analog audio outs for up to 7.1 surround sound. They are color coded. "Green" ("L") is for your "front" speakers; if you only have two speakers then you'd use this port. The other's are for their corresponding surround speakers (i.e center/subwoofer, surrounds, rear surrounds).
Going off of the specs for that rig, it does appear to have a 56k modem. That would be the smaller card occupying the white PCI slot towards the bottom of your motherboard. It also appears that your computer has a built-in wireless card as per the spec sheet (Integrated Realtek 802.11b/g Wireless Networking) found here http://www.gateway.com/product_spec....ecid=529668104
I'm quite soundly convinced the card in question is your wireless adapter, as the antennae is internal, apparently. Does the card look any thing like this:
If so- that's your wireless network adapter. Going off of your picture in this post:

On the bottom in one of the pci slots there is a card that is attached to 2 phone jack slots on the back of the computer that say "LINK" and "POWER." 2.) The top "card" in the small black slot is connected to two red and green lights on the back of the computer that say "LINK" and "PWR".
I think the new graphics card should go above this in the pci-e slot, but there is not room for it to fit. What are these cards already there?
First reference the larger, bottom picture. I recognize what appears to be the same type of antennae used in laptops. Referencing the bolded in your quote above:
1.)That is your 56k modem, mostly used for dial-up internet connection and PC Fax.
2.)The red LED "PWR" would indicate that the wireless network adapter has power. If it is plugged in and your computer on, likely this will be continuously lit. Like most laptops this card can be disabled, doing such should cause this light to turn off. The green LED "LINK" likely will never be constantly lit. It should flicker randomly when you are connected to a wireless network, functioning more as an activity indicator. While lit that indicates activity over the wireless network, when dark it indicates no activity. Thus the flickering as the activity will be varied. It also serves to indicate whether you have a connection to a wireless network. If it does flicker, you're connected. If you're not connected there will be no wireless activity and thus no flicker.
So now the question is- do you need this to get online? Well, are you connected to your modem (or router) via a hardline? It'd be an ethernet cord (will look like a phone chord, but much thicker and with a larger connector), and it'd plug into the ethernet port I pointed out to you earlier in this post (referencing the photo of the output ports on your motherboard here
it'd be item "G"). If you have a hard line connected to the ethernet port then you can safely uninstall the wireless network adapter. This will allow you to install the GTX460.
The other possibility is that you are using a dial-up connection. If so, then you'd have at least one phone cord feeding into the dial up modem, that's the item in the bottom white PCI slot with the phone jacks. If this is the case, then you can still safely remove the wireless network adapter and install your GTX460.
If none of those two are the case, then you are using your wireless network adapter to connect to the internet wirelessly, via a wireless network. You'll have to run an ethernet cord from the back of your router to the ethernet port on your motherboard (item "G" if you'll referrence the photo of the output ports for your motherboard here
Now... word of caution- the GTX460 does require a 450 watt power supply. I don't care how Gateway rates their PSUs, a lack of 150 watts is a rather large discrepency. I would urge you to purchase at the very minimal a 450 watt power supply just to be safe. That GTX460 requires a *minimal*
of a 450 watt PSU. So even if your power supply is capable of that much wattage, you *will*
be pushing it near it's limits. Doing so is putting a great deal of strain on the unit, and thus causing it to fail much earlier than when under nominal load. And if your power supply does fail, there is the possibility it could take out multiple components (could fry your processor, motherboard, new graphics card, etc)... or it may do no damage at all. Either way, not worth the risk in my opinion. If you're on a budget then delay installing the GTX460 untill you can afford a new PSU. A little bit of patience never hurt nobody.
Hope this helps.
