Given that F<sub>1</sub>(-c, 0) and F<sub>2</sub>(c, 0) are the left and right foci of the ellipse G: $$\frac{x^2}{a^2}+ \frac{y^2}{4}=1 \quad (a>0),$$ point M is a point on the ellipse, and MF<sub>2</sub> is perpendicular to F<sub>1</sub>F<sub>2</sub>, with |MF<sub>1</sub>|-|MF<sub>2</sub>|= $$\frac{4}{3}a.$$  
(1) Find the equation of ellipse G;  
(2) If a line l with a slope of 1 intersects with ellipse G at points A and B, and an isosceles triangle is formed using AB as the base and vertex P(-3, 2), find the area of △PAB.
