Compute the net force along the direction of the plane, making sure to subtract friction (if any) and the component of weight along the plane (W sin A).
Net force = mass x acceleration
How would I go about calculating the acceleration of a mass being pulled up an inclined plane at an angle.
Given - mass, and presumably angles

First, take the mass. It has weight mg. break that into components, normal to the plane, and down the plane.
fn=mgcosTheta
fd=mgsinTheta
You I hope remember friction is dependent on the normal force.
Pulling force-fd-friction=mass*a
This problem is standard fore for physics test, make certain you can do these on your own.

But what about the second angle? There is another one besides theta that I don't know what to do about - but that explanation just helped alot with all the other problems!
on the angle of the rope pulling the object,you have to break that force into components: one is normal to the surface, that affects the normal force used in friction. Now the force parallel component is the pulling force. Sorry I did not see that at first.
