hey friends...i request you all to pls help me out...im damn confused...

im planning to make a website by March,2011 in which i will be using HTML/JSP and Mysql as d/b. however, i have a few doubts abt. Mysql....

1) on the mysql site, there are many packages available to download. which one should i d/l. im using windows 7 and netbeans IDE?

2) im confused whether i should use only the essentials package or the complete package ? wats d difference between both as far as query processing time is considered. my web application needs lowest query response time.

3) any tutorial site covering all the queries of Mysql....???

4) is there any other d/b that i should use instead of Mysql ? im not willing to invest any money since im a student and i have previusly worked on oracle and sql.

thanx a lot in advance.
