Answer 1

As per as, your code you want to rewrite class Mage_Customer_Model_Customer.

But in config.xml, you try to rewrite model class Mage_Customer_Model_Product and in default magento this class does not exist. I sure you want to rewrite class Mage_Customer_Model_Customer. So, you should

Change

<product>Lesson_Test_Model_Customer</product>

to

 <customer>Lesson_Test_Model_Customer</customer>

at config.xml
