Correlation questions

We want to find what questions in survey are highly correlated to overall
score. We picked a group of questions based on practical meaning and
calculated the average score of these questions for each survey. The
correlation between the average score and overall score is pretty high.
Here are the 3 questions:
1. How do I determine the cause of the high correlation? Is it because
these questions really have big influence on overall score or just
because the average score is the result of two many questions (it's clear
that the correlation between the average score of all questions and
overall score is 1)?
2. How can I find a group of questions that are really high_correlated to
overall score? ( I know the correlation between each individual question
and overall score)
3. Are there any good references on correlation analysis?

Please send your help to 75371.1671@compuserve.com. Thanks in advance.
