I had that exact bike with 1998 Marzocchi Z2 BAM forks on it and it was great. Be careful with the age of the forks you buy as from 1999 I don't think you can change the steerer on the forks to a threaded one which you will need on that bike unless you change the headset and stem. Changing the stem may not be a bad thing though as the best things I ever did with that bike were put suspension forks on, put a shorter stem on and put some bars on with 25mm rise (V brakes are also a good upgrade on the front and then you don't need forks with a cable stop).
Best of Luck
