Answer 1

Are you lagging just trying to play System link games between the 2 Xboxes directly, or only when connected to Xbox live?

The amount of traffic from a 2nd Xbox shouldn't cause much lag unless your wireless signal isn't too strong- it could be one of the Xboxes has trouble communicating with your wireless router, or is getting interference from other devices (like 2.4ghz cordless phones, neighbor's wireless networking equipment, etc) If the two Xboxes are sitting right next to each other, try putting some distance between them, like 10-15 feet.

**** UPDATE ****

I just looked at the picture of your setup, and one thing stands out. If that Belkin device is really a HUB, then replace it with a switch!!

Sometimes people use the terms hub/switch interchangeably, but hubs are older technology that only lets one device "talk" at a time. So connecting a 2nd Xbox on a hub means things get slower, whereas on a switch, each connected device can communicate at full speed, simultaneously. You can find 4-port switches dirt cheap these days- a used one from Ebay would be fine.

In fact, most wireless routers have a 4-port switch already built-in. If you have two network cables long enough (like 25-footers), you could connect them directly from the back of each Xbox to the ports on your router, and completely skip the hub/wireless gaming adapter combo. In fact, you might want to test it that way first, just to make sure that eliminates the lag.

If the router is too far away from your Xboxes and TVs for network cables to reach, then just replace the Belkin hub with a switch. The brand shouldn't matter- D-Link, Netgear, Belkin,Linksys whatever. Just lose that hub :)

You might also consider a Buffalo Airstation, which can replace both your hub and wireless gaming adapter with a single device.

Here's an article that explains the hub/switch difference in more detail:

Answer 2

You need to get a wireless adapter for each of your Xbox's. The gaming adapter is only really ment to be used with one device and sharing it causes a bottleneck. You'd probably benefit from a faster router, either gaming or N. But with an N series router you'd need new wireless adapters too.
