So I just got Lugia in Soulsilver. Now there is two things I want to do: Get the Entei/Raikou and defeat the elite 4.

For Entei/Raikou, I got them to 1 hp (pikachu-colored pichu: endure & endeavor). Raikou is asleep. I still can't catch them with quick balls or ultra balls.

For the elite 4, these are my pokemon (I'm not really a stat-trainer or anything, and I'd rather not change the pokemon as I am trying to prove a point to someone.):

Quilava-Lava Pume, Ember, Quick attack, Swift.
Weepingbell-Vine Whip, Sleep Powder, Cut, Sweet Scent
Red Gyrados-Waterfall, Aqua Tail, Surf, Whirlpool
Sudowoodo-Rock Slide, Block (using it on Entei/Raikou), Rock Smash, Strength
Pidgeot-Fly, Wing Attack, Quick Attack, Twister
Togetic-Metronome, Extrasensory, Flash, Ancientpower

I can't loose the HMs, need them for traveling and stuff. Don't want to loose Sweet scent or Metronome, but will replace Sweet scent if necessary. Any move change suggestions?
They are levels 36-40, working on getting up to 45 (or should I aim higher?)
Thus far, my strategy has been run-in-and-keep-trying-until-I-win. I've even won a few by using hyper potions on my gyrados until the opponent is struggling, then sending in my pokemon weak to that type.

I don't really understand the stat stuff, so I just train until I win. Would someone explain stats/EVs/whatever? I don't get that either.

Yeah, I need alot of help. Sorry I'm so messed up.
