HELP, clutch/ shifter problem

hey guys, yesterday i was driving home and when i was doing so i heard something go under the car. i though i just ran over something, because i felt it hit my floorboard. after that i tried to down shift and my shifter was really loose. it felt like a civic but worse. at a red light i tried to put it in reverse first and second but i couldnt . some thing fell out and i dont know what it is.i had to drive it home in third gear. right after i got my other car and went back to the area where i happened and found these parts. i have an 01 standard gts. any thoughts on what it is or what i have to do?

il upload pictures of the parts as soon as i figure out how to upload them -_-
