OK guys, I finally finished the job, and here are my observations/opinions for anyone who has this problem in the future. When your car's clutch pedal starts to stick in the down position while your shifter is in a gear, and nd your car starts to slowly creep while sounding like it's going to stall, then it is purely a hydraulic issue within your clutch cylinder lines. Before anything, look for any leaks. Spray everything (clutch slave and master cylinder, and all hoses, and clutch fluid (which is brake fluid) reservoir tank). If there are no visible leaks, I would go still go in the following order. My first part replacement suggestion is to replace the clutch slave cylinder, as it is the easiest to replace. Then bleed the system (through the slave cylinder). If that does not work, move on to replacing the clutch master cylinder. If there are no signs of leaks, more than likely it is this peice, but it is moderately difficult to replace, as it is a ***** to install! Once you replace both cylinders, and find no leaks in the hoses, then your car's clutch line hydraulic problems will go away. I guess I am writing this up, because the whole time I was getting scared that it MIGHT be the clutch.
THESE SYMPTOMS DO NOT MEAN THE CLUTCH! As I've said before, I have driven plenty of cars until the clutch has gone out on me, and it never acted like this. Research the symptoms of a failing clutch, and you will see it is very different from the hydraulic problem. My car is now running great. I know that I will have to change the clutch soon, but I do not want anyone to confuse the two problems. I would hate for someone to do a complete clutch job, which is very difficult/time consuming, if they are simply having a hydraulic issue. Many people/mechanics were assumming this as my problem, as you could not see a leak.
Good luck to everyone, and thanks again for everything!
