Hmm... well, if you're going for the badges, the first gym is a flying type gym. So you'll want an electric Pokemon to take them down. In terms of general strategy, since Ponyta is a fire type, it's weak against water, rock, and ground types. I believe there are Hoppip on Route 29 that are grass type, which should take care of those other than Rock.
Most Breeders seem willing to give new Trainers a price break on eggs - and all Pokemon come from eggs, as strange as it sounds. Keeping a diverse team is good for traveling, even if you plan to specialize in a few types of Pokemon. I find having at least one psychic type on hand is useful if only to translate for other Pokemon.
