[RPG] What happens when I can prepare more spells than I have slots to cast them with

I have to agree that the wording in the original rules is not a 100% explicit. It is clear that you cannot cast spells of a higher level than you have access to, but can you prepare them? The Pathfinder FAQ has a more complete answer, emphasis mine:

No. You only get the bonus spells if your class level grants you access to those spell levels. You can't even use them for lower-level spells. See page 16, Abilities and Spellcasters section: "In addition to having a high ability score, a spellcaster must be of a high enough class level to be able to cast spells of a given spell level. "

For example, a 1st-level wizard with 18 Intelligence has (according to table 1–3: Ability Modifiers and Bonus Spells) 1 bonus spell at spell levels 1, 2, and 3. However, he can only use the 1st-level bonus spell because as a 1st-level wizard he only has access to 1st-level spells (his class-based number of 2nd- and 3rd-level spells per day are "—", meaning "no access to spells of this level"). As soon as he becomes a 3rd-level wizard, he gains access to his 2nd-level spell slots and can use that bonus 2nd-level spell slot from his high Intelligence, and likewise for 3rd-level spells and bonus spells at wizard level 5.

Basically, ignore the columns for higher-level spells on table 1–3: Ability Modifiers and Bonus Spells until your class grants you access to those spell levels.

The Pathfinder FAQ is considered official in the Paizo community and is binding for Pathfinder Society (http://paizo.com/pathfinderSociety/faq#v5748eaic9qy5).

Each day, you can prepare a total number of spells as listed in the table, plus any bonus spells you get for a high Wisdom score.

For example, a 1st-level cleric with 18 Wisdom: the table says 1+1 first-level spell slots, which is to say 1 from the cleric list and 1 from one of his domains. He also gets a bonus first-level slot from his high Wisdom. So, ignoring his domain spell slot, he can prepare two spells that day.

That means he can prepare, for example, 1 use each of divine favor and magic weapon. Or he could prepare 2 uses of divine favor, or 2 uses of magic weapon. And the next day, it’s the same deal but could be any cleric spell or pair of cleric spells. But he has to choose how many of each to prepare each day.
