Possible upcoming team for me...

[Chairman Kaga]

I?m not really a technical trainer like a lot of people so I?m clueless on a lot of things...I?m planning to make a good team for Colosseum but I?m unsure about some of the finer points of training... if it?s not too much trouble, I?d like to know what pokemon do I train to get the right EVs and what natures work in my favor for the attribute which should be most accentuated on these pokemon...


Note: all levels unknown...let?s presume at least 75.

Salamence @ ?

Dragon Claw
Aerial Ace
Flamethrower/Fire Blast
Roar/Rest/Hyper Beam

Blaziken @ ?

Flamethrower
Sky Uppercut
Bulk Up/Mirror Move
Earthquake/?

Metagross @ ?

Meteor Mash
Psychic
Iron Defense/Rest/Light Screen
Hyper Beam/Brick Break/Shadow Ball

Zangoose @ ?

Swords Dance
Crush Claw
Shadow Ball
Flamethrower/Fire Blast

Regice @ ?

Ice Beam
Amnesia
Toxic/Hail/Double Team
Explosion/Curse/Earthquake

Gyarados @ ?



Dragon Dance
Thunderbolt/Hyper Beam
Hydro Pump/Surf
Attract/?



...yeah...I?m pretty much clueless...I was also considering such pokemon as Absol, Glalie, Altaria, and Lanturn. Are any of these good substitutes?
Thanks for all your help!

Earthquake should be given to Metagross

Blaziken should have Sunny Day

Gyarados' Dragon Dance is useless

Salamence should have Crunch

Regice@Chesto/Lum Berry

Rest
Ice Beam
Explosion
Superpower

That's my personnal opinion....
