Are we gravitationally attracted to things outside the observable universe?

No signal at all, including gravitational waves, could have reached us by now from outside the observable universe (technically, the particle horizon). This is by definition.

So, no, there is no possible way for Earth to have to been affected by any causal signal emanating from outside of the observable universe.
