I think you'll end up with more points as much as you can cast the number of spells in your group.(That didn't sound right)
Ok, you have one 7th level spell point right now. Eventually you'll learn both spells and have at least one point for each of those spells. Can you get up to 9? I'm not sure... I've never done it before.
1. If you change professions and you don't have all the spells on a level (I'm guessing you've got either Malikto or Kadorto when you change), you will always get every spell in the level. 2. If you are not in a profession that uses those spells, you will have exactly the number of spells that are in the level.
PROTIP: Try leveling a priest to @lvl. 13 or so, change him to a mage. Repeat process. Change to a Bishop. Watch as fun ensues. You'll gain spell numbers slowly, but eventually you'll have a basic bonus priest/mage character that can identify items.
You'll be fairly old (25-6), but if you have Wizardry 2, you can transfer the character to that scenario and - if you find a few Stones of Youth - make him 19 again.
