They are separate, complementary concepts which can occur separately or jointly. The String Theory multiverse includes many different regions of space created e.g. by many pockets of cosmoc inflation, possibly with different laws of physics. Many worlds quantum mechanics posits that within universe, reality splits up whenever a "random" decision at the quantum level occurs, and there are a set of parallel realities in which all possible results of that particular process occur.
That being said, there are some smart people who claim that some inflationary multiverse scenarios can be mapped to the quantum many worlds in a kind of isomorphism between spatially parallel universes and quantum parallel universes. Kernel should like this 
I'm really not convinced though that this works.

And Einstein thought his theory of everything was hard!

General Relativity is still difficult, but compared to what your average string theory grad student has to master nowadays, it's pretty basic.
His theory of everything though failed, maybe for precisely the reason that he didn't know how to deal with quantum physics. He tried to stick with the methods that led to his success in General Relativity and thought he could explain everything with those. For decades it looked like he was completely on the wrong track with that (because quantum theory is so different). These new developments seem to suggest that there's a possibility of putting everything into a geometric picture as Einstein envisioned it, but in any case much more complicated than what he thought, because so much more physics has been discovered since the 50s....

So do you think its plausible that the tiniest particles are traveling through a non-spacetime dimension?

What do you mean by non-spacetime dimension? For me, dimensions are by definition a part of spacetime.

From what I understand, which is very little so please be patient, is that there a fabric of spacetime spread across the universe. Is it possible that the fabric keeps matter in general order but it is "tearing" or splitting from the expansion of the universe? And the tiniest particles are able to bounce in and out of the "fabric" The dimension would be outside of our purview until we figure out a way to experiment more fully at quantum levels.
