Pretty low, go to the ruins of alph for the old amber and the helix/ dome fossil depending on which version you have. You have to use Rock smash on the rocks there to get them.
Alternatively, the root/claw fossils are at the cliff cave once your national dex opens up, same method to get them as before.
You can only get it on Heart Gold by getting a specific fossil.
Viridian Forest. Morning and Day times there is a 6% chance of getting a Pikachu level 4-7. In the night there is a 5% chance of getting a level 4 Pikachu.
No.
You cannot get Skull Fossil or Armor Fossil in Pokemon HeartGold.

Theres a guy in the pewter museum who will turn your fossil into pokemon.

You can get it by smashing rocks using Rock Smash in the Ruins of Alph.
You have to trade it from HeartGold, in the ruins of alph when you use rock smash on the rocks you can find the Dome Fossil(for kabuto) but that's only for SoulSilver, the Helix Fossil(for Omannyte) is only found in HeartGold
take it to the pewter museum and talk to the guy with the black hair he will take your fossil and make it into an omanyte
in a cave after you've beaten the elite four, on the way to the safari zone
No you can't. You can only get it in Soul Silver. Instead you find a Claw fossil in the place where you would find the root fossil- Cliff Cave. You cannot find a Claw fossil in Soul Silver.
