Would there be different degrees of ability, something that could be trained and strengthened, or is it more you get what you're born with kind of powers?

All the above, actually. Powers develop over time and usage of them, so they can be trained. Someone who had their power up until their elder years could very well be a master.

And, some peeps are born with their power, but it's uncommon to say the least.
