Have you tried using an x86 version of the compiler?

Any of them. All arduino are essentially the same. Only memory, clock speed, and form factor differ.

Which board you get depends mostly on the space you have available. You'll need to choose a balance between features and physcal size. Using the XBee alone would be a good solutions ,since you wouldn't need an arduino on both ends that way.

That's all possible. The lookup table can be a simple array that you store in memory. You would need to use something like a binary search to find your temperature (http://en.wikipedia.org/wiki/Binary_search_algorithm). It would be easier to find a best-fit formula that relates voltage to temperature, and use that.

You can store values to an SD card to look at later. I have a tutorial on how to do that:http://www.youtube.com/watch?v=5v5A3j7Rrco
I'll have a tutorial on how to use an LCD screen soon as well.

IF i only use te Xbee antenna hooked up to the accelerometer, is there a speacial program for the Xbee to display the data on the computer?
what programming language would i be using to write te software i need for tis system? (i know java, c, c++)

2) can i use an accelerometer to measure the force applied to a surface? ( i know there are force/pressure sensors but I'm trying to use few hardware components)

Jeremy, How do you access the serial number of an atmel controller from the chip?
thanks,
Dennis Riggs

Connect to it via the ICSP programming pin, and use a program like AVR studio to read the chip info. You could also do a dump using avrdude.

XBees have the ability to transmit signals from a few digital I/O lines. You would just need to feed those same lines into an arduino on the receiving end, then hook that arduino up to the computer via serial. You can write the computer software in any programming language that can talk to a serial port.

I can't think of a way to use an accelerometer to measure surface force.

Do you have a sample code that can do that?
thanks,

You don't need any code. You do, however, need an ICSP programmer, or a second arduino that you can configure as one (http://arduino.cc/en/Tutorial/ArduinoISP). Once you get that hooked up to your computer, you can connect to it with AVR studio, and look at the serial number, etc. (http://www.atmel.com/microsite/avr_studio_5/default.asp?source=redirect)
