Just a bit more and at the right age I would think you'd be able to break 500 at a much lower current. Though I wonder if your goal now is just an arbitrary number above 500 or a certain rank of skill or going all the way in the same path as the great blacksmiths.
For now just want to switch Round for Oblivion on my headgear to get +10 max in exchange for a critical penalty, and then cap all will skills to keep 130% crit after doing so. No real other plans, I always just take it easy, play as I go along and rank whatever feels right at the time.
