Given an ellipse C: $$\frac {x^{2}}{a^{2}}+ \frac {y^{2}}{b^{2}}=1(a＞b＞0)$$ with left and right foci $F_1$ and $F_2$, respectively. Point A is the upper vertex of the ellipse, $|F_{1}A|= \sqrt {2}$, and the area of △$F_{1}AF_{2}$ is 1.
(1) Find the standard equation of the ellipse.
(2) Let M and N be two moving points on the ellipse such that $|AM|^2+|AN|^2=|MN|^2$. Find the equation of line MN when the area of △AMN reaches its maximum value.
