WIFI (802.11b - Prism2 chipset) Driver interfaced with LwIP TCP/IP stack

The MIPS Atlas board in the above picture runs a Webserver, with the following modules:
RTOS - uCOS-II v2.61
TCP/IP stack - Lightweight TCP/IP (LwIP)
Net Apps - http & ftp
MAC drivers - PRISM2-PCI (Wifi 802.11b), Philips / RealTek-PCI (Ethenet)
File system - Virtual RAM file system.

Hardware details:
MIPS 4Kc 32-bit processor running at 80MHz
MA311 PCI card from Netgear
Philips SAA on-board ethernet

Software blocks on the target (HTTP & FTP web server)

How to connect with the wifi server using a PC running redhat 9.0

Browse the wifi server’s page on mozilla using its IP address (http://169.254.95.135 -- assuming 169.254.95.135 to be the IP address set on the wifi web-server).

How to connect with the wifi server using a PC running redhat Windows

Browse the wifi server’s page on Internet Explorer using its IP address (http://169.254.95.135 -- assuming 169.254.95.135 to be the IP address set on the wifi web-server).

To do
1. Right now the wifi web-server serves just static html files with gif images. Need to extend it to serve Dynamic html files (SSI (cgi), php, jscript or ...).
Need advice on choosing the right dynamic html protocol with the following points:
a) Easy to implement on the embedded server (simple code).
b) Less processing power.
c) Need the following features: 1. Display status of LEDs & switches, 2. Control LEDs, 3. Enter values on a edit-box for setting some parameter.
Also please let me know if there is free C source available for one of the DHTML parsers.(email me: embeddedneteng@yahoo.com).

2. Need to include modules to get some parameters on the traffic flow (iperf). Please let me know any information on such tools available on the net (other than iperf).

Thanks for taking time to check this out. Let me know your comments on this & also email me if you need more information/help on this.
