First of all, is it really necessary to format? You can use repair option on Windows CD and obtain almost new OS with your old settings and programs.
Second, if you really want to format (format only your system partition I hope) you will need special disk backup and imaging software
. I prefer True Image (I use it for over two years and it really never let me down). It can create incremental backup of your C: partition for example and save it on any other one. After Windows reinstallation you will be able to restore this image and have old settings and programs.
But you can just create rescue bootable CD with TI and you will need only 1 CD for it. Then after drive formatting you'll be able to boot ATI from the rescue CD and restore partitions from archive you created earlier.
