Well first off I would like to say that Gold and Silver were my favourite pokemon games. I recieved a game boy color and both games on my birthday, so thats something I hold near and dear. But anyways...
The first Round of the Elite Four was easy for me. The first time I ever beat it I had this team, that I can still remember now, after about 7 years. I had
Level 48 Feraligatr
Surf
Slash? (can't remember)
Water Gun (lol)
Ice Beam/Ice Punch (can't remember which one)
level 42 Scyther
Slash
Swords Dance
Toxic
Double Team
level 40 Dragonair
Twister
Thunderwave
Surf
hyperbeam
level 40 Dragonair
Dragonbreath
Thunderwave
dragon rage (haha)
hyperbeam
Level 39 Red Gyarados
Waterfall
Surf
Hyperbeam
Whirlpool
level 20 Farfetch'd
sand attack
crap
crap
crap
(The pokemon I switched in to revive someone else)
So thats what I did. It was fairly simple, but the Dragonite that knew Thunder was a pain. Eventually got off an ice beam.
But but but the Elite four round two, after completing kanto was much harder. I used this team.
Feraligatr lvl 70 something
Surf
Ice Punch
Thunderpunch (I think...)
Slash
Arcanine (traded over from red at lvl 18 something) lvl. 71
Extreme Speed
Take Down
Fire Blast
ember(hehehe)
Scizor lvl. 66 (sadly...I liked scyther better)
Slash
Swords Dance
double team
(X-Scissor????? I don't remember this one)
Umbreon lvl. 73
Faint Attack
flash
scary face
(some other stat reduction)
Machamp
Cross-Chop
Vital Throw
Submission
foresight (why??lol)
Dragonite lvl 80 (I liked him a lot)
Outrage
Thunder
Ice Beam
(Fire Blast or Surf; can't remember)
That was it. I also used these for Red. But anyways, correct me if I have made any errors, impossibilities of G/S. I may have been mistaken.
