Koga the Poison Shinobi

The gym's right by the Pokemon Center.  Can't miss it.  The trainers around the
gym will use primarily psychic-type Pokemon, so if you've got a good Bug type
lying around, now would be the time to use it.  The Ghost types you can catch
in the Pokemon Tower are also Poison types, so they're weak against Psychic
attacks.  In other words, don't use them.  Once inside, go straight up and
straight left to fight Juggler Nate.  Once he's down, go straight right to
battle Juggler Kayden.  After him, head one square right, then straight up
until Juggler Kirk attacks you.  Go up again when you're done with Kirk to
battle Tamer Edgar, who will use the first Poison type of the gym, along with
the odd Sandslash.

From Edgar, go left along the north wall of the gym till you spot another
trainer, then feel your way down to him.  After beating Tamer Phil, go to the
square one left of where he stands (or was standing, if he caught sight of you
and moved) and go down two, then left one to fight Juggler Shawn.  Skip past
the trainer listings to get directions to Koga.

Sorry, I like a break between listings.  Anyway, from the square one up from
Juggler Shawn, go one left, four down, then straight right to end up by Koga.
Talk to him to battle.

Leader Koga (Payoff: $4300)

Pokemon (Level)   Type             Weakness(es)                            EXP

Koga's a real bastard Poison-type user.  His Koffing and Weezing both levitate,
so you can't use Ground-type moves like Dig or Earthquake against them.  If you
have it, Sand Tomb is still effective.  Otherwise, send a Psychic type out to
beat up Koffing, then switch to a Ground-type to battle Muk.  It's powerful,
but it's very vulnerable to such moves as Dig and Earthquake.  Muk likes to use
Minimize to raise its evasion power, Acid Armor to raise its defense by a ton,
and worse, Koga has Hyper Potions at ready to heal it or any of the rest of his
lineup.  If you happen to get poisoned, cure it right away!  His type of poison
can hurt you in a hurry.

Now, Weezing is a whole new brand of hurt.  Its level is likely much higher
than anything you've currently got, so you'll have to fight smart.  Psychic
types will likely take it out quick, unless Koga reserved his Hyper Potions for
his final batter.  If you haven't got a Psychic type, odds are you'll have a
tough battle ahead of you.  Ground types also aren't effective due to Weezing's
levitating power, so odds are you'll have to deal with accuracy loss,
poisoning, and a lot of annoying rounds ahead.

Victory against Koga nets you a nice prize purse, including the SoulBadge.
This badge lets you use Surf whenever you want, so you can now go back to the
Safari Zone and get a few more items.  You'll also receive TM06, Toxic.  With
that gym out of the way, the road is clear to Saffron City.  Well, not really.
If you didn't get the Tea from the old woman in the Celadon Mansion, you'll
have to go snag it and give it to the guys at the guard house so they'll let
you through.  It doesn't matter which one gets the Tea, that one guard will
distribute it to the others.
