When you evolve a Pokemon, its CP circle stays as full as it did before.
As a result, it really doesn't matter in which order you boost a Pokemon. However, you should keep a few points in mind:
- Powerups cost more Candies the more CP a Pokemon has (based on a Pokemon's level).
- Powerups cost more Stardust the more CP a Pokemon has (again, based on level).
Cost will increase every second powerup.
Therefore, it makes sense to power up a Pokemon until it is near the upper end of your CP ring. As the ring stays in the same place, it will give you a rather decent CP per Candy ratio.
For example, if a Pokemon's max CP was 515 and it is currently at 425, it would make sense to power it up to 500 or more. At that point, you should evolve it, provided you have the candies.
Overall, you'll still be using fewer candies because you're doing most of your evolution on the lower side of the scale, and using the Evolution mechanic to sharply spike the Pokemon's CP.
So far, Niantic support only provides these categories for submitting requests:
- Request a nickname or team change
- Delete my Pokémon GO account
- Report an issue with a Gym or PokéStop
- Report inappropriate gameplay
- Report inappropriate Trainer behavior
- Report a bug
- Help with PokéCoins and premium items
There is no category that might fit in with issues around changing an email address, but you may make a request anyway in e.g. the "nickname or team change" category and share your experiences.

If you want to change your name from the settings menu it will ask you twice, whether or not you want to be renamed.
After confirming both questions it will check for availability. So yes... the procedure is pretty much the same. If it's available you get it right away with no further confirmation request.
