Eevee can not evolve into porygon.
To evolve the Pokémon Eevee in Pokémon HeartGold and SoulSilver, you can choose either of the two choices described below:Train Eevee in the nighttime when it has max happiness.Train Eevee in the nighttime when it is around a Moon Shard.Steps have nothing to do with the evolution of Eevee.
You can give the Upgrade to Porygon and then trade it to a friend to make Porygon evolve into Porygon2, in order to evolve Porygon2 then give a Dubious Disc to Porygon2 and then trade it to someone and it'll evolve into a Porygon-Z.
In Pokemon HeartGold and SoulSilver, an Eevee cannot evolve into a Glaceon. You can trade with other trainers from Diamond, Pearl and Platinum to get one.
You seem very confused about the world of pokemon. Eeevee doesn't evolve at a level. You need an object to evolve it, but I forgot how, so go to www.wikapedia.com and search Eevee, or if you want to search on Bulbapedia. One of them will show how to evolve it on the evolutions page. Eevee can also evolve into ALOT of other things. Hope I helped! :)
Sorry there is no further evolution of porygon z
Evolve Eevee, or trade.
get an eevee and evolve it into a thunderstone
To make Eevee evolve into an Umbreon, you have to level it up with high happiness at night.
A water stone
The Icy Rock is not in it, which is needed to evolve an Eevee into a Glaceon.

Can only evolve from Eevee if it gains a level while on Route 217, so you must trade an Eevee over to Diamond, Pearl, or Platinum and evolve it there, since there is no Route 217 in HeartGold and SoulSilver.
