Shadow Lugia is not in HeartGold.
you need a couple of dark Pokemon levels 60-70 that know dark type moves, that should be enough

Lugia its easier.
No. Lugia for SoulSilver and Ho-oh for HeartGold. Yes, you just get them at different times. You get Ho-oh in Johto and Lugia in Kanto in HeartGold, and vise versa in SoulSilver.
it wont with celibi but it might work with lugia or dark lugia could be a shiny lugia.
Lugia can be found in whirl islands only if you have the silver wing.
heartgold is better because lugia is stronger in heartgold and lugia is stronger than ho-oh

You can't get Dark Lugia in Pokemon Silver, Gold, or Crystal. You can get Dark Lugia in Pokemon XD though. For Pokemon Silver, Gold, and Crystal it is just the regular Lugia.
