Soul Silver E4 Advice

I'm currently in the grind for the E4 (first time) probably going to break about 50, but I've constantly been losing pokemon in training (literally no good grinding anywhere). I only have 4 seriously trained 'mons, and need some seriously planning:

CYN- Typhlosion: Flame Wheel, Cut (I miss Swift), Smoke Screen, FlameThrower

BRIE- Noctowl: Air Slash, Extrasensory, Hypnosis, Reflect

WAVE- Gyarados: Ice Fang, Aqua Tail, Surf, Dragon Dance

FARADAY- Ampharos: Strength, Charge, Discharge, Signal Beam

(EDIT: Current levels are mid to high 40's, still grinding them out.)

I'm thinking to add Earthquake on CYN (maybe instead of Cut), Dark Pulse on WAVE (Dropping D.Dance), and maybe Shadow Ball on BRIE (don't know if I should drop Reflect or Hypnosis, leaning to Reflect).

The only things not dead in my boxes are low level Rattatas, Geodude, Zubat, and a lvl 22 Golbat. I might try to train up the Geodude, but my record this run leans on any of these dying in the grind.

Any advice on this?

EDIT: Final changes as I go into E4 (yay for emulator speedup):

CYN lost Flame Wheel and Cut for Blast Burn and Fire Blast (dat lack of coverage, but power)

BRIE is unchanged.

WAVE switched Surf and Waterfall

FARADAY dropped strength for Light Screen

AND,

I did train up a Geodude and now have added: AEGIS the Graveler with: Rock Blast (risky), Earthquake, Stone Edge, and Defense Curl (was going to switch with Sub maybe to buy some time for item use, I don't think she'll be very useful).

EDIT II: Results are in.
