No: That is at the upper end of normal or a little out of range on high end depending on which lab you are using. Levels that high are usually associated with supplementation. Depending on how much, how frequent and by which method ( oral, sublingual, injection) you can back off on dosing frequency if you like. If you feel better keeping it at that level then no harm done.

Not particularly: As there really a limited suggestion of toxicity related to vitamin B12 intake.
