Implementing Microblaze in Xilinx Virtex4 (ML401) ?

Good morning 

   I have a project where I need to embed microcontroller in a Xilinx
ML401.This project consist a GSM which connect to a
microcontroller(ATMEGA8535) and the microcontroller is eventually
connected to Xilinx Virtex4 (ML401).It is actually road traffic light
implementation for Emergency Vehicle Preemption System.
   My friend told me that I could do this by implementing  a Microblaze
microprocessor in the FPGA on the ML401 board and then connect the GSM
modem serial line to the Microblaze instead of through the external
microcontroller board.  Then I could port the code from the external
microcontroller to the Microblaze.
   My problems are :-
1)Where could I get the microblaze free tutorial? Is the tutorial in
VHDL?

2)After attaining the microblaze code, how should I use it? For the ML401
, I am using software named Xilinx ISE 8.2i . Should I use this software
to run the microblaze code?
 
    Your aid is really being appreciated. Thank you very much

I have implemented the MicroBlaze soft processor on a Xilinx ML403
board. You can read more in my blog: http://www.fpgafromscratch.com
