Start from the Pokémon Center, go North a little and then turn left on the first path. Keep going left, then down and go inside the building with a sign in front of it. You are now inside Goldenrod's Underground.
Hope its helps :D
You need a key that you will get from saving the president of the radio station from team Rocket, you have to beat the 7th gym before this happens.
The north end of the underground tunnel (I assume you mean in Goldenrod City, not that other tunnel in Kanto) there is a branch off to the left side. Follow that branch and you will see a little camera sitting in the hall and to the left of that a counter with a hiker and some other dude sitting at it. If you just want a picture in a team rocket outfit, talk to the non-hiker. If you want the dress-up your Pokemon station, talk to the hiker. Have Fun!
there isn't a radio tower in firered and leafgreen, but in gold, silver, crystal, heartgold and soulsilver its in lavender town. You need to go through rock tunnel to get to lavender town. You wil need flash to get through rock tunnel
The powerplant is in the same spot it's in, in Red, Blue, Yellow, Gold, Silver, Crystal, Fire Red, Leaf Green, Heart Gold, and Soul Silver. East of Cerulean City, south of Rock Tunnel. You need to surf to get to it.
once you are done helping lance in the underground, he will give you a clampearl that knows whirlpool
It's in Kanto. You have to surf eastwards from Newbark Town, then go through a waterfall cave etc
A guy in the underground tunnel will give you it.
