transmission issues

ok, so I am driving home from work today at ~60mph and reach my off ramp. I push in the clutch and my whole jeep starts shaking HARD. Release the clutch and shaking stops, but I am arriving at my stopsign. once again, clutch in, shaking commences. try to shift gears, pops out of 5th, wont go into any gears. finally man-handle it into 2nd and it started shaking HARD once again! so I limp the rest of the way home in 2nd, try futiley over and over to get it into gear, won't go into anything but 2nd. releasing the clutch in neutral results in shaking as well, but not near so much.
Those are the symptoms. some ideas I've been given are the throw-out bearing, possibly hydraulics. I crawled under it and *forgive me for not showing my mechanical ignorance* noticed the rearmost part of the transmission has a plastic thing with a seal around it, it is slightly *showing the seal* out. I pull it all the way out with little effort, and the whole assembly is plastic. there is pink stuff near the top of the inside of this "thing". also of note, my 4 wheel drive doesn't feel like it was disengaged, but talked to a friend and he said it may be acting like it's in 4 high, but not really engaged. was planning on addressing that at the earliest convenience. Also of note, my starter bolt is VERY tight, but not all the way in, resulting in difficulties in starting it every once in a while. I don't know how tight the bolts are mating the engine to transmission, but all looks good there. everything I've looked at so far seems to be pointing to the throwout bearing, I'm just trying to see opinions here, anyone able to help?

Sounds like the slave cylinder went out to me. That is the the thing that engages the clutch with hydraulic pressure. It works kind of like a master cylinder for the brakes. If the internal seal went out it will not fully engage the clutch and wont leak either. Have you checked the fluid in the reservoir?

The slave cylinder is still a suspect. The fluid can bypass the piston if the seal is bad and there will be no external leaks or missing fluid.
