How do you calculate the sample size for a survey?

Dear friends,
I am not if this is the right way to go about posting here but I need some assistance.
Does anyone here have experience in surveys? I need some guidance. I am designing a nationwide survey on students dietary habits. Let's say the country is divided into 5 parishes with the following number of schools and students:
Parishes----Schools-----School population
A -----------20 ---------8,000
B ------------9 ---------20,000
C -----------40 ---------10,000
D -----------10 ---------20,000
E -----------6 ----------6,000
1. How do I select a reasonable nationwide sample of students from
the entire school population for this study?
2. Parish Based Approach.
Would it be reasonable enough if I randomly select a specific number
of schools (for example 5 schools) from each parish then add up
the number students from these five schools and randomly choose a
determined amount of students for the study? What should be my
sample size?
Suggestions Please.
Thanks in advance.

Hopefully it will.
Are you doing this survey as part of a course?
