Answer 1

In the database aspect of your question:

To normalize you should make sure you don't have repeating information, generally don't store fields that are calculated, and make sure the relationships of your tables are one to many if possible. Assign meaningful primary and foreign keys that are unique to their tables. Referential integrity is key! I'd also stay away from null values.
