salamence is weak against ice and dragon type moves. So use it's weakness.
It depends on what moves and how powerful they are.

Use any decent ice type move and because Salamence is a Dragon/Flying type, it will be 4 times as powerful as normal. Salamence should die but if it doesn't then you're probably screwed.
There's a small room that opens up after you beat the elite 4. It will have a TM on the land and a 25% chance to find a bagon. Level it to 50 and it evolves into a salamence.
No it is not REQUIRED to beat Orre Colesseum to get Dragonite (but it IS required to Snag ALL the other shadows in the game to unlock Dragonite)

cath groundon or maybe you can reach it with a salamence I did it on that way
At level 55, a DRAGONAIR evolves into a DRAGONITE.
Great just of course watch out for specific trainers: Ice type trainers can easily defeat scyther and dragonite, Rock type trainers can beat dragonite, scyther and flareon, Electric type trainers can beat feraligatr and scyther. Your sixth Pokemon can be whatever you want just remember to be balanced.
