Hi,
Answers in brief:
http://www.oracle.com/technology/ora...ch_tuning.html
This link, just gives a small explanation on your first question

Sql hints are like you are asking the query to do something in a particular way. You specify in the query to use a certain index etc:

eg: select /*+ index(scott.emp ix_emp) */ from scott.emp emp_alias

Cheers
