Re: Spacetime
The best explanation I've ever seen is A Brief History of Time by Stephen Hawking.
It's an awesome book, and explains quite a bit about general relativity.
As for what spacetime is, it's, well, space and time. The two things are the same is the gist of it. Time is a dimension, just like height and width.
There's more to it than that, but Sir Stephen does a much better job of explaining it than I ever could.
