For the first question : use conservation of linear momentum and conservation of energy. That's all you'll need to do.

Be sure that you apply momentum-conservation in both the x and y direction of the frame of reference.

The formula they gave looks weird...That $\vartheta_{2}$ is written as a function of $\vartheta_{1}$ & $\cos\vartheta_{2}$

Since the problem reminds somehow of the classical HS theory of Compton effect,i assume that $\vartheta_{2}$ can be found exactly...

I AGREE (hey that feels strange ). The formula i get has a v1' and a cosine of theta_1, instead of v1 * cos(theta2). It seems quite stupid to me that we'd set up a formula for theta 2 that actually contains the theta2
