One minor addition to the matter of driveshaft angle: The angle per se is not what's most critical ... the important thing is that, with the car in a normal ''at rest, weight on the wheels'' posture, both u-joints be working at the same angle. For example, if the driveshaft slopes downward from front to rear, the downward angle between tranny tailshaft and driveshaft must be matched by the opposite-direction angle between driveshaft and pinion shaft at the rear end. Another way to think of it is that the tranny tailshaft and the rear axle pinion shaft should be parallel to each other. If this is not the case, driveline vibration and stress on the u-joints can result. Adjustments are generally made by tapered shims between the rear springs and the axle pads.
