Unfortunately, until you source the cause of the leak(s), I can't be of anymore help (sorry).
It sounds like something has "let go" in a big way

but there are several possibilities as to what could be. My first impressions are either catastrophic HG failure, cracked head or you've thrown a rod and damaged the crank case (sorry to be Mr Doom and Gloom) but I hope I'm wrong (which is quite often).
