There's no way in any Pokemon game that you can capture every Pokemon in a single version. You have to trade between other versions to receive the Pokemon FireRed cannot capture.
You will be spending a lot of time catching, training, hatching eggs, trading, and using action replay codes. To find the location, go to www.serebii.net.
