All spell progression is as per the wizard class. (It may be worth noting that Spellhoarding is LA: - rather than LA: +0.)

Bonus spells apply individually to every spell progression that qualifies. There could, theoretically, be a class that lacks a version of the bold text here:
Like other spellcasters, a sorcerer can cast only a certain number of spells of each spell level per day. His base daily spell allotment is given on Table: The Sorcerer. In addition, he receives bonus spells per day if he has a high Charisma score.
Such a class would then not gain bonus spells. I'm not sure if that ever occurred.
