Windows Server 2003 + WiFi Network + Domain + Active Directory Configuration

This seems to be a long question, and I need every bit of help, so I'm offering lots of points here that would be split if necessary, I'll begin with describing the situation, then asking the questions.

SITUATION:
--------------

* A company with 9 PCs (Desktops & Laptops), all Windows XP Pro installed (only one that have WinMe installed)
* All PCs have wireless cards (or built-in in case of the laptop) except the Windows ME PC
* A server PC would be purchased (A normal P4 3.0 GHz 2MB L2 Cache, 1 GB RAM, SATA HDD)
* We have a 2 Mbps ADSL connection through a NETGEAR Wireless Router/Firewall
* All PCs have access to the Internet through the Router (again, except the WinME PC)
* The router supports RADIUS keying
* We have several departments (Sales, Marketing ...) with several PCs each
* I'm going to install Windows Server 2003 on the server PC so it would act as a domain


QUESTIONS:
---------------

1) I have never configured or worked on an "Active Directory" or a "Domain" on Windows Server before
What do I do since installing the Windows Server 2003 till I get the following scheme:
- Every department would only be able to see the other PCs in their department
- Share the printer in each department
- Make a shared folder on the Server PC for each department that they alone could access
- Define the priviliges for every user in the company

If you could provide me with a link that has screenshots too, it would be great, I'm sure there are many tutorial pages but I can't find them.

2) I want to be able to control the other PCs internet access through the server PC (remember the WiFi part)
i.e. control websites they visit, control bandwidth, have a log of their internet activities.
And how do I configure the router and the server to do that?

3) Can I connect the WinME PC by a crossover cable to another PC with WiFi and have it join the network, or must I purchase a wireless adapter too?

4) I want to be able to control the server from my laptop without having access to the server room.

5) What if a guest arrives with a laptop that has WiFi and wants to quickly connect to the internet to see his mail?
Any fast and easy way?

6) Will the specs I mentioned for the Server PC be enough?

7) Does Windows Server 2003 contain Exchange Server so that users could use Outlook to e-mail each other?

That's all the questions I could get of my head right now, and please I need accurate and detailed answers.

Thanks all for the help.

edit: What with 500 points at most thingie? I want to put 1500 points for this question!!!
Please moderators, is there any way to add more points?

Hi,

OK, I'll try and answer some of the questions, my fellow experts will most certainly answer the rest.

1. Setting up Active Directory in just a couple of clicks, without having a decent understanding of what you're doing could be tricky, if not dangerous. However...
Every department would see other PCs from the same department : yes, no problem, by defining OUs.
Share printers : no problem, publish them in AD, with the proper permissions
Shared folder : Classic scheme, with NTFS permissions
Privileges : same

Many things are well explained, and you'll also find a ton of screenshots.


2. The best way is to set up ISA server. Problem : you don't want to setup ISA server on a domain controller.

4. No problem, you can use the remote desktop feature and define proper permissions to only allow admins to have remote control.

6. Yes. I would add a couple of things : having only one DC is quite dangerous, and at least you should add RAID / hotplug capabilities.

7. No it doesn't. You have to install Exchange Server. Tricky mission too...

HTH
Cheers
