If I were you, I would get them all to level 45, although when I beat them mine were level 44.
Aim for an Alakazam or heracross and you should be fine.
You should evolve all your Pokemon that can evolve to their final form. Everyone of your Pokemon evolve by level except for Togepi and Heracross. Togepi evolves by happiness into Togetic and then a shiny stone to get a Togekiss. Heracross can't evolve so he's good. Hope this helped!
You can evolve a boy Kirlia into Gallade with a dawn stone.And Female Snorunt into Froslass.

Togetic cannot be found on Diamond and Pearl, check the question "How to get Togetic?" for more details on how to get it.
sorry no trainers have a togetic in Pokemon soul silver but you can get a togetic when you get a togepi evolve it by happiest and it will evolve to a togetic.
you battle togetic at the Pokemon league
Togetic doesn't evolve by level. A Togetic can only evolve by a Dawn Stone.
Togetic's evolved form is called Togekiss.
its good but remember to evolve machoke, kadabra, and graveler. replace quagsire with gyarados.
togapi is a spike ball Pokemon and it evolves into togetic the happynes Pokemon and togetic evolves into togakiss the jubbaly Pokemon you evolve togapi by getting a high frendship level and level it by 1 and you have a togetic you evolve togetic into a togakiss by using a shiny stone on togetic.
Togetic is not in the game.
