The best way to understand the format and meaning of the fields is:

• Create a record in Odoo

• Activate Developer Mode

• Hover over each field you in Form View (the record you entered) to see the field name

• Export those fields to see the format of the CSV file

• Add your own records in that file (which is more likely to go back into Odoo than a CSV you make from scratch)

The data model is available by looking at Settings --> Technical --> Database Structure --> Models 

Whether you can setup Odoo by yourself or not is really a question of comparing the time it would take you to get familiar with your skills and comparing that to how much you would save.  Consultants can spread the time it takes to learn Odoo over many projects - you can't.  If your time equates to a very small amount of money, perhaps it is worth it.

Odoo offers training at http://training.odoo.com/ - it is worth paying for this (or training through a partner/consultant) because an hour you spend yourself will never be as productive as an hour you spend with organized training.
