Dusclops can be found in the Safari Zone in Pokemon Soulsilver. The rarity varies.
Porygon2 is a 2nd gen pokemon and does not appear in Pokemon Red. That aside, both of Porygon's evolutions occur when you trade it while it holds certain item. Up-Grade for Porygon to Porygon2, and Dubious Disc for Porygon2 to Porygon-Z.
It is impossible to obtain a Porygon2 without trading. You can get a Porygon and trade it with an Up-Grade or you can get a Porygon2 from the GTS but there is no way to get Porygon2 without trading.
