do I need to assign an IP address and default gateway to the vlan?

No, not unless you want to route it with the other vlan.

I've been asked to create a seperate vlan for a public wireless internet connection. I have a seperate cable internet connection coming into my modem and then a linksys router. I created the vlan 99 and tagged 2 ports on my procurve to vlan 99. I forbid all other ports for vlan 99 and forbid the 2 ports on all other vlans. I plugged the wan side of the linksys router into one of the ports and a laptop into the other port on vlan 99. I configured the helper ip address for vlan 99 to be the linksys router. I'm still not able to get an ip address from the linksys when plugged into port 2. what else do I need to do, I don't want any traffic from vlan 99 to contact anything else and vise verse.

How to create a seperate isolated vlan on procurve

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
