get them abit higher and buy lots of max potions stuff like that, yeh go for it

no,get them at least lv.65 all of them

You can go after the Elite 4 whenever you want, so long as you're good at battling.
Stats would help.
Sceptile:
Get something better than Absorb. Mega Drain at the least. Pursuit is okay, though
Sceptile doesn't need it and Elite 4 Trainers do not switch their Pokes out. Quick attack
is also a bit pointless because of the fact that Sceptile's speed stat is high up. Maybe
teach it Leech Seed, Bullet Seed, or Double Team/Agility. Double Team/Agility will make
Bullet Seed a Godsend. You are going to want at least level 50 Pokemon.
Kyogre:
Never use Hyper Beam. Replace it with Surf. Take advantage of Kyogre's Drizzle Ability.
Teach it Thunder for the sake of being accurate with rain.
Loudred:
He isn't going to help your team much. If you want a high health Pokemon get a Milotic, or
if that is too much for you Slakoth has titanic health (My lv 100 Slakoth has 504 HP =).
Get rid of Strength for some stat lowering or buffing up move. Otherwise Stomp won't get
you anywhere.
Pelliper:
Water Gun? Really? Surf it up with Pelliper, and I guess Supersonic would work, but
Pelliper won't do much damage. Maybe Confuse then switch in Hariyama for complete tandem.
Hariyama:
Moves are okay. Switch out Rock Tomb for Seismic Toss maybe. Rock Tomb has pitiful damage.
There's not much else to say, Vital Throw will eviscerate Steven.
Gardevoir:
Uhm. Utilize Gardevoir's Godly attack stats. Get something in there like Psychic, maybe
Double Team and Attract for sake of being a jerk, and fill in the last spot with anything
high attack that isn't Psychic type.

Parsay, if you don't feel like breeding to get those TM's you have already used, 6 Pokes
at level 60 should get you through the Elite 4 without many problems, regardless of the
Moveset.

Your team is okay, you just need a little work at actually knowing what types of Pokemon
are going to damage yours, and what attacks you need to use for countering.
