Unless you never go out of your way to do extra objectives or gather runes/bone charms with the Heart, then you shouldn't find yourself stuck later game due to not having good enough skills. You could hypothetically get through this entire game without ever unlocking half of the powers if you wanted.
If you're just playing this for the first time though, then I wouldn't worry about missing too much unless you're really anal about completion. I missed several runes/bone charms my first playthrough and had no issues.
