Hey,
I want to make a pretty simple XBee control,
which modules would i need?
which shields, how many arduinos and how many XBee units.
I've read about them, but i'm not sure what i need :S
I hope you can help.
You just need a UART connection and 3.3V power and GND connection.
You'd just need a 3.3V voltage regulator and thats it.
and that will make a communication between what?
I'm not sure i follow :S
o.k. xbee Version 1 are the easiest to set up for point to point link.
Xbee are not 5v tolerant, so you need to power it from 3.3v and send 3.3v to the Rx pin via a voltage divider.
You need 2 xbees of the same type !!!!, version 1 don't talk to version 2s.
And a pair of something like :-

if i buy
a XBee Explorer USB,
and a XBee Explorer (non-USB),
and 2 XBee 1 mW modules
How can i control the XBee explorer (non-usb) with the arduino?
Because as i understand i can control XBee explorer USB directly from my computer, and send signals to the non-usb that's linked to the arduino.
Is that the way it works? and if so, can you give me tutorial links ? 
What do you mean control ?
If you mean!!!! Make a link to the other module on the p.c ? very easy.
Eg any thing that gets put on the Rx pin gets sent out of the Tx pin , Yes
Change setting ? , not very easy .
I just swap modules and do the setting up on the p.c , then connect it to the Arduino
so

is good enough?
with the

Yes , that will make a radio link between the Arduino and a p.c.
I have 2 Xbee explorer without the usb plus 1 with the usb.
But I use mean for a Arduino 2 Arduino link.
awesome, because i want to be able to radio control my arduino from my PC ;D
a radio link is o.k , but it will not update the program without mods.
which is to do with, you can`t get it to reset.
So via radio link you need to press the reset button .
So say if an Arduino was plugged into the PC via USB and has an XBee shield with a series 1 XBee sitting on top.
The other XBee module (no shield no nothing) has a 3.3V to pin 1 and GND to pin 10....will they be able to coommunicate?
