How many spells can you pickup?
You can unlock all of them. You will still be gaining skillpoints after you reach level 80. You can only slot one spell in each skill slot though, but you’re able to swap them out when you’re not in combat.

You can level up after reaching 80, but it only grants a skill point and not an actual level. additionally, there are far more skill points gained through discovery than you will ever need for skill purposes.
