The first question is dependent on what you expect the educational system to accomplish. I expect that the educational system increases the number of people capable of making meaningful contributions to society. Naturally such a system benefits from assessing that capability to attempt to ensure that it is accomplishing that.
Things that are shown not to contribute to that end should be removed if they are detracting from the system's capacity to that end.
The question of accuracy is a matter of practicality. In short, a more accurate and precise measurement in any system allows you to figure out more information. There is no situation in which having that information would not be slightly more helpful. However, since the problem has an unknown number of input variable and an unknown number of output dimensions, we can only attempt to correlate whatever testing methods we have with our guesses of the quantity we are actually trying to measure. In short, we would like to measure intelligence and ability and value more accurately, but we can only barely begin to describe what they even are, and as such attempting more accurate measurements of them is completely absurd.
Fewer or more subjects should be considered against points one and two. It is too complex a question to answer without a sizable quantity of statistical data.
How much should be spent is just as complicated, since it is impossible to educate someone for free, as to educate people require resources in the form of permanent things (such as information, knowledge, space to work in, etc), disposable things (such as paper, pencils, pens, computational capabilities), and the time of other people. Equally complex is the question of who should be responsible for paying for it, but that returns to point one: To whom does the educational system hold enough value that they would be willing to pay for it?
For how long people should be educated, see points one and two again.
Of course, what the educational system is actually for is open to debate. The difficulty of applying statistics to exams to divine information about a person's potential future contribution to society is questionably open for debate if you have a decent counterpoint.
