Clutch slave cylinder replacement HELP please!!

[dieselhate]

Im in a tough spot, gotta work on monday and i think that my clutch slave cylinder is bad. I was taking off up a hill and all of a sudden the clutch got really soft. I turned the truck off, then all of a sudden the clutch was extremely hard and i couldnt get the clutch down far enough to get it to start. long story short, what ive done so far is: go to advance auto and picked up a new slave cylinder (hoping thats all the problem is) i came home crawled under my 99 f350 7.3L, almost TOO easily pulled of the slave cylinder and the rod was very flimsy feeling. I then turned the bleeder valve and bled the fluid dry (which now i know is going to make bleeding air even more difficult but, oh well.) my immediate problem is unhooking the stupid hydraulic line from the old cylinder itself. its got a "quick connect" which is anything but, theres two empty holes at the port of the new cylinder and two holes that have some kind of small holding clamp inside the holes. do i need a special tool or what? AAAHH! Also, If anything i described, you have any extra helpful info about surely would be mucho appreciated. bleeding the system and all. Is this a common problem and does this problem trigger a million other problems? thanks a lot guys for looking.
