drain the oil and check to see if it is gritty / has metal in it. If it does, see above

More to the point, you missed a shift and overrevved the engine badly. By missing third and hitting first, you forced the VQ to rev beyond its limits. It's a noob mistake, and it sounds like it's resulted in severe engine damage.

There is NO lockout for first gear on the 6-speed manual tranny. There is a double cone synchronizer on first gear that makes it difficult, but if you FORCE it, terrible things can result! Manual transmission use does entail a certain amount of skill and judgement, but the OP isn't the first one to miss a shift and won't be the last one, either.
