There is a path between Cerulean and Vermilion, and between Lavender and Celadon.
Vermilion city is south from Cerulean city to get there though you need to use the underground path.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
First got to Lavander town, then go west until you see a house with underground path.
But if you want a water stone, trade one over from firered/leafgreen on a Pokemon or you can find one in the underground.
Not in Pokemon leafgreen only in Pokemon Firered never ever in Pokemon leafgreen And in Pokemon firered it is rare in power plant not available in Pokemon leafgreen?
you should go to gamestop

On Pokemon Pearl's title screen, if the Pokemon LeafGreen game is in the GBA slot, click on "Transfer From LeafGreen" and you can choose six Pokemon from LeafGreen to transfer to Pearl, but be careful-you can't trade them back.
