Do you have a hardware firewall? You can use MAC address filtering on the firewall to ensure that no outside computers connect to your network.

Yes, what you need is called port based authentication (802.1x).  Depending on whether or not authentication is granted or not, you can drop them into different VLANs (networks).  Depending on which vlan they get, they can do different things, such as surf freely, or not.

Here's a white paper about it:

802.1X Security - Designing a Secure Network

Date Published:
21 SEP 2004  
About the White Paper:
The theme of the paper is business critical systems security, first illustrating the importance of and potential difficulties in protecting information that traverses networks; then examining network security as a holistic concept before focusing specifically on the IEEE 802.1X enterprise edge security standard. In addition, the paper demonstrates how RADIUS used in conjunction with 802.1X provides a long-term, secure, and low-cost system for network authentication, authorization, and accounting. Also discussed is how 3Com's integrated portfolio of security product solutions fully supports 802.1X and layered network protection, making it easy to improve network security.
