Okay, no problems with Ninetales? Good, we can move to Venusaur.
I've seen plenty of variations on the Venusaur set- some people prefer the all-out attacker Venusaur, some people prefer a defensively set Venusaur that can take out opposing Pokemon with weaker yet still powerful blows, then there's the Venusaurs that differ between a physical attacker and a special attacker.
If you want a physical attacker of a Venusaur, I'd suggest:
Venusaur @ Life Orb
Ability: Chlorophyll
252 Atk/252 Spe/4 HP
Nature: Adamant (+Atk, -Sp. Atk)
~Power Whip
~Earthquake
~Growth
~Leech Seed/Seed Bomb/Double Edge
The fourth is really up in the air- if you want a support move, or a move that can help get HP back, choose Leech Seed. If you want a second STAB move, go for Seed Bomb. If you want a more powerful attack, overall, Double Edge is the way to go- but be warned- the recoil from Life Orb and Double Edge combined can really sap from your Venusaur quickly.
If you want a special sweeper of a Venusaur, you'd want:
Venusaur @ Life Orb
Ability: Chlorophyll
252 Spe/252 Sp. Atk/4 HP
Nature: Calm (+Sp Atk, -Atk)
~Giga Drain
~Sludge Bomb
~Growth
~SolarBeam/Leech Seed/Petal Dance
You won't have to worry about Life Orb's draining powers for this set- spam with a Giga Drain, and with a +1 Growth alone, you could OHKO a Scizor. Solarbeam, presuming you still have Sunny Day, would be tied for the best special for STAB Venusaur has. Leech Seed would make you an HP earning machine if you use Giga Drain, plus you would have a slight edge over the opponent. Petal Dance is the grass equivalent of Outrage, and under a single Growth and having STAB and a Life Orb, has monstrous power. However, the bad side of this is that it gets confusion 2-3 turns later- best to use this move near the end of the battle.
