With regards to your clutch you should have 8 friction plates one of the 8 has a slightly larger internal diameter this takes the clutch boss spring, the spring takes up the slack in the clutch plate and stops them chattering about, a lot of after market clutches don't come with this plate so you will have to get one and a boss spring if you don't have as well.
When you reassemble the clutch make sure that you fit the clutch push rod and the the small ball bearing before fitting the front pressure plate, when you have done the clutch spring and bolts up you can the adjust the the small push rod ( the wobbly bit as you call it ) do this with a small cross head screw driver and a 10mm spanner, slacken the nut and gently turn the screw in until you just feel it just touch the ball bearing then re tighten the 10mm nut while holding the screw.
When you have re fitted the casing and cable adjust the cable taking up the slack but leaving a little play at the clutch leaver, some times you may find if you are using a pattern clutch that the plates are a little thicker so if you find that the clutch is still slipping you may have to take the casing off again and back the screw off a quarter of a turn or less to stop it slipping, but never over tighten this as it pushes the clutch plates apart and will cause clutch slip. I hope this is of help please let me know how you get on Skip
