my oddish evolved at level 21 maybe around the 20s
In SoulSilver, Oddish will evolve into Gloom at Level 21 however Gloom can evolve 2 different ways, you can use a Leaf Stone on it in order for it to evolve into Vileplume or you can use a Sun Stone on it in order for it to evolve into Bellossom.
Personally i would say as soon as you get gloom evolve it.
Your Aron will evolve at level 32 into Lairon.
