Eevee:
Go to Bill's house in Goldenrod, talk to his family.
Find Bill in Ecruteak, talk to him.
Go back to Goldenrod and to Bill's house, he'll be there. If you have an open slot in your team, you'll get eevee. I'll update when I find info on the stones.
Stones:
After you show Bill (route 25) a Lickitung and receive Everstone, he'll ask and reward you as follows:
"The one with leaves coming out of its head."-Oddish. You'll get a Leaf
Stone.
Either "The one with many tails" or "The one with big jaws." This varies
depending on your version, but it's either Vulpix or Growlithe. For this,
you get a Fire Stone.
"The one with the multi-colored core, that's shaped like a star."-Staryu.
Your reward is a Water Stone.
"The really popular one, before it evolves."-Baby Pokemon Pichu. Collect
a Thunder Stone for your efforts.
But well, here is, I fear that's the only way besides Mystery Gift.
