"To is an infinitive, as in to walk"

Incorrect, 'to' is used in order to show infinitives, it is not an infinitive itself. It is also a prepostion, wich you failed to mention. You also forgot to mention that 'too' is also used as and adjective to describe quantinties that exceed the needed amount.
