i figure (and hope) my clutch isn't blown but what would cause this. basically its going all the way to the floor and not coming back up. i can manually pop it out with my foot but obviously not driveable.

besides that, i also can't put it in and gear

clutch fluid out maybe?

 

have you checked your clutch fluid? it will take you 10 seconds.

 

Check to see if you have in Fluid in your Clutch Master Cylinder. You could have just ran out. Add and pump the clutch and see if it puts some resistance back into the pedal.
If it does, keep an eye on he Clutch Fluid level for awhile and see if you are losing fluid quickly. If you are you have a leak some where. If you can't see a leak in/around the Clutch Master Cylinder or the Slave Cylinder, you probably have a leak some where in the hard line. Which is very common for Preludes. There is a Damper in the Clutch Line and it is **** to leaking. If it's the hard line leaking, I recommend replacing the complete Hard Line with a Stainless Steal Braided line. That's what quite a few people have done on here to remove the stock hard line which has a multitude of places to leak and to remove the Damper. It's much shorter and easier to handle that the stock line and probably cheaper.
I just did this myself the past week because I was having the problem I mentioned before.
If you'd like to do this I can hook you up with everything you'll need to fix it, just let me know.
