Do I need both Red and Blue to finish the route Pokedex?

Yes. Each version locks away a handful of route species. Ekans, Oddish, Mankey, and Growlithe stay in Red, while Sandshrew, Bellsprout, Meowth, and Vulpix belong to Blue, with Scyther and Pinsir split the same way. Trading with the other version is the only way to fill those gaps.

Where do I get the fishing rods in Red and Blue?

Three rods, three givers. A fisherman in Vermilion City hands over the Old Rod, which only ever hooks Magikarp. The Good Rod comes from a fishing fan in Fuchsia City and adds Poliwag, Goldeen, and other common catches. The Super Rod, waiting on Route 12, reaches the rod-only rarities listed here.
