Networking & wireless: Landlord's Wireless Connection

Landlord's Wireless Connection

I'm just about to move into a new appartment shared with a few others. The landlord is provinding a free wireless access (via a ADSL connection into the property distributed by a consumergrade wireless router in the hallway) with my rent.

Now, I'm a fairly savvy user I want to move my current set up to the new place.

I have a standard ADSL router off which I have connected a slingbox (configured for external viewing) two Windows servers (running XP Pro), a PS3 and an iMac via the wired (gigabit) part of the network.

On the wireless network I have an iPhone, iPod Touch, Airport Express (for AirTune), two Macs, Windows Mobile phone and two IP video cameras (with external viewing).

Ideally I want to establish my own wired and wireless network in the house using Power Over Ethernet for the wireless camera's that I'd move to the wired network. So I'd need to be able to connect at least eight devices to the wired network simultaneously. And of course have the wireless connection so I can use my notebook wirelessly too.

I'd also like to assign internal IP addresses manually for some computers based on Mac address, for example have my notebook always be 192.168.1.105 every time it connects to the network.

I want to keep my network private from the other tenants but connect to the shared internect connection into the house.

Would I be able to run a CAT5 lead from the shared router into my room to another router and set it up like so? What complications might I face?

Your help is much appreciated.
