In triangle $ABC$, the sides opposite angles $A$, $B$, $C$ are $a$, $b$, $c$ respectively, and it is given that $3a\cos A = \sqrt{6}(b\cos C + c\cos B)$.  
(1) Calculate the value of $\tan 2A$.  
(2) If $\sin\left(\frac{\pi}{2} + B\right) = \frac{1}{3}$ and $c = 2\sqrt{2}$, find the area of triangle $ABC$.
