My T-5 is TRAYASHED- any ideas?

[429mustang]

My trans has been whining for a while, 2nd and 4th grind almost all the time. The last week it got worse, when I decelerated it made a grinding/whining/chattering noise, so I've been holding in the clutch when I slow down. Today I was going to the mall to finish up my christmas shopping, about 1/2 mile away from the mall my trans totally got worse, it sounded like it was going to blow up in every gear, it grinded and vibrated the whole car, even when it's in nutreul (I re-typed the word nutreul a few times, now i can't tell how to spell it right) , when the cars parked it's quiet when in nutruel with the clutch pushed in, but as soon as you start to let off it started to sound like ****'s breaking. I'm guessing it smoked and probably not worth rebuilding, which is sweet cause now I have 2 cars with broke-*** transmissions.
Anyway, I ended up pushing my car back to my house (about 2-3 miles away) with my dads S-10.

Not that anyone cares, but I figures I'd write about my mess of a car. Feel free to comment on wether to rebuild or get a used T-5 off ebay. A new tremec is out of the question for at least a couple months. Also, I just noticed theres a spot to attach a picture, so I'm attaching a pic for anyone who wants to see my 86 Mustang or my 85 Astrovan w/sbc 355.
