linux router + authenticator+bandwith limiter

Hi guys,
I have a scenario like this.

I have five different buildings in the same locality connected together thru one Access Point. Each building has a client radio (Senao) and thru the AP+ClientRadio the hosts in diffrent buildings can access the internet which is available the LAN leg of the AP.
The ClientRadios are in Bridge mode, thus totally transparent.
Now, I want to sanitise the network

I want to place a linux box behind the ClientRadio(one per building) that will be able to perform the following.

1. Route the traffic fromeach building to the AP LAN side. plus Firewall (Drop broadcast and any unwanted packets)
2. Authenticate users on each building.
3. Perform bandwidth shaping for users in a building

I also intend having four servers at the AP LAN side (Webserver, Mailserver , DNSServer and a Proxy server(Squid-Web_caching)).

For the first function, I want to use MASQUERADING-HOWTO from Please will this be enough?
For the second function, i want to use FreeRadius. I have never configured one before Please help on this
For the third function, i.e the traffic shapping per host, I learnt squid can do it but I dont know how and I dont think it will be reasonable to have multiple squid instances on the network. so please help me out. its a giant step I want to take.
The distribution to use is FEDORA core 6.
Sorry for this Epistle.
please assist in any form, be it resources, links, clues, or even advise.

I think this may help setting up freeradius:
It's has a collection of useful links not Gentoo specific.

This link also might look interesting because you are authenticating your users over a wireless network:

For bandwidth shaping if you want to explore linux possibilities through iproute2 command this document is a must: (I never used squid)

Good luck

Thankx noisebleed,
I already have most of the links mentioned above the problem I had with those Freeradius links is that they are for older CVS versions of freeradius and if u try using them with the CVS we have arround today, they do not fit in perfectly (most especially in configuration files).

Please guys I still need more links and enough advice
