Yeah that would be fine, but do you need the four ports?
If not you could just buy something like this and save money.
If you don't need the ports and are looking for something subtle you could get one of these
Also I'd like to stress I'm not endorsing either product, I just picked quick examples.
But yes, that is fine.
Without a wired connection, I don't think you can use that router to connect the apartment wifi. Most home routers do not have an option for a wireless connection to a WAN (the apartment network). Looking through the manual for this model, that looks to be the case here.
Sounds like the ethernet port you found doesn't connect to anything. If it did, you could configure your router as a switch (turn off DHCP and set it's IP range to be different than the apartment network) and then use it for your devices, letting the apartment network manage the DHCP.
As it is, probably the only thing you can do, without getting a new router that can wirelessly access the wifi there, is to use one of the wireless enabled computers to connect and then use Internet Connection Sharing from that computer to provide internet to all the devices.
EDIT: Something like this would let you connect to the apartment wifi and provide you with a standard router to provide wired and wireless connection in your residence.
EDIT 2: This device has better reviews at Amazon, for a similar price.
EDIT 3: Or you could use something like this to connect to the apartment wifi and then port it to your current Netgear router and let that run your home network. You'll need to consider placement so that you have wired access for the devices that need it.
Please define what exactly you mean by "wireless extender." Because when I went looking for one, I was trying to find one of these.
