Clutch problems?

i got a 03 s10 4 cyl manual, when im shifting the rpms get rly high and i get little movement. also today when i was going slow in a parking lot turning there was a big bang almost like the fell. anyway its making weird noises and rpms are high and i also want to know if i might need a new flywheel or a new clutch, i am concerned and low on cash and i need to get to school. thanks
