Wrangler Clutch Problem

2002 Jeep Wrangler X, 6CYL MANUAL, 63,000 mi.
My Jeep hasn't shown any signs of having problems and was running fine on Friday and after sitting in the driveway over night, not driven, the next morning the clutch felt a little different than usual (harder than normal to press in) and makes a chattering sound when pressed all the way down. The other problem is that, the Jeep can shift into any gear without the clutch being pressed in at all and it won't drive at all. It will start and everything seems/sounds fine until the clutch is pressed down to the floor and makes a sound. I am in Germany right now and it will be much cheaper to order the parts from the states and take them to the mechanic but I have no clue what parts I would need to order and I would also like to have an idea of what the problem is so that I don't get overcharged for work not needed. Thanks in advance!
