Clutch acting odd

Well i think my clutch is going out, but i'd just like some oppinions and if it could be something more than just the clutch.
It engages and shifts just fine, but at times ( i think this si my slave cylinder ) the clutch pedal will stick to the ground and i have to use my toe to pop it up then it's fine, also on a hard acceleration, mostly in fourth or ffth but sometimes third at the end of it's rpm range, the clutch will act like it's disengaging itself repeatedly almost ike an abs rake would act on a car.

Like the rpm of the engine goes up and the truck doesn't accelerate accordingly? That's indicative of a slipping clutch, time for new pressure plate, new disc, new throwout bearing, and machine the flywheel. If you just throw in a new disc, doubt that it would last very long.

sory i haven't got the quoting down yet lol, but no it's more like a jerking, at first you go into a loss of power say in fifth at 70, i'll start dropping to 55 60, once i hit 50 i gear into 4th and just let the clutch catch, it will catch fine, but as you start to re enter the gas pedal a jerking and chugging happens, like the flywheel is slipping or the pressure plate is being released repeatedly.

But i plan on getting a new clutch, (Edit) 100$ and some odd dollars, they quoted a fan clutch earlier like wtf really ) dollars at advance for the whole kit n kaboodle,

( Update) The same guy i got my radiator off of happened to have a transmission, brand new with ( used but new enough sorry ) 35K miles on it, all i need is a clutch kit and i'm good, figuring im low on cash and was wheelin an dealin with him even got a new tailgate and chrome lined taillights, stock style lights just instead a black outer trim it's chrome. but well why not go aheead and pick up a basically brand new complete transmission and just replace mine not knowing how old the one i it is or mileage on it, figure hey i got a chance can't pass it up especially on these trucks it seems.
