Given the parametric equation of line C1 as $$\begin{cases} x=2+t \\ y=t \end{cases}$$ (where t is the parameter), and the polar coordinate equation of the ellipse C2 as ρ²cos²θ + 9ρ²sin²θ = 9. Establish a rectangular coordinate system with the origin O as the pole and the positive semi-axis of the x-axis as the polar axis.

1. Find the general equation of line C1 and the standard equation of ellipse C2 in rectangular coordinates.
2. If line C1 intersects with ellipse C2 at points A and B, and intersects with the x-axis at point E, find the value of |EA + EB|.
