IDK favorite Pokemon maybe? Just a recommendation you might want to get your SID and do shininess first, for that one is easier (and less error prone) to get than good IVs. Also must be something you have good IV'd parents for.
That's the norm for HGSS games. On DPP it will be different.
On the other hand, I think you should try breeding something. Only when you complete it can I be certain you are ready to go out and face the world of Wifi.
