Try fighting and ghost types. Fighting is super effective and normal has no effect on ghosts.
Also, use an Aron/Lairon/Aggron for the non-Focus Punch Slaking and the Vigoroth. Facade will only do 26.25 damage on these, assuming the opposing Pokemon is not under a status condition. But really, you should use ghosts.
Norman has a Slakoth (Level 28), Vigoroth (Level 30), Slaking (Level 31) so I suggest you train a party of mainly Fighting type Pokemon to an average of about level 30 before you challenge Norman. Good luck!
After you get the 4th badge go to petalburg city and enter the gym go through it then fight Norman for your 5th badge.
take the meteorite
after you beat flannery you go back to where your dads gym is and beat that gym hope it helped :p
I would say any fighting types.
After you beat Norman in Sapphire, head next door (the house to the left of the gym). There, Wally's parents will give you HM03 (Surf).
After you beat Norman he will tell you to go to Walley's house, next door, and his parents will give it to you.
Norman is your Dad or in other words petalburg gym leader.
