Sounds like youre asking how to EV train it?
If you dont know how about how to do it then here is a good site that can help you learn how
http://www.serebii.net/games/evs.shtmlAs for what you should do.
Use 10 Protein and Carbos on it to save some training time.
As for what to kill, you can get everything done on Route 1. Patrat and Lillipup will give you 1 EV for Attack and if you surf in the water you'll find Basculin who give 2 EV's in Speed each.
The EV spread you probably want is 252 Attack, 252 Speed, and 6 HP
