Aside from the rules which show how many new spells these classes get automatically as they level, is there any guideline as to how many spells they SHOULD be able to gain through other means? Other means being finding scrolls, purchase from NPC, etc.
And as a secondary, how much does the level of access provided by the GM to new spells affect the character's power overall?
there should be spellcasters in various towns and cities you go to. You can pay them a small amount to scribe from their book.
It shouldn't matter that much, you should be able to get the majority of the spells you use each day from the ones giving from your class, so not having 1 or two spells still leaves you with the majority and some slightly less desirable but still good spells.

Thanks, this comment lead me to the Settlements table in the rules, which shows a town this size should provide access to spells up to 3rd level for purchase. Up to the GM, of course, but it's nice to have something to point to.
