D/P/Pt Tourney Team Help

So, some of you may remember this, and now I'm working on my team for it.

I probably won't go all-out with EVs and IVs (still haven't gotten the hang of IVs yet anyway), but if It'll help I'll try to EV train and Nature breed (full set of Dittos!)

I haven't settled on final team members, but I have a few.

Here's what I have so far:

Vaporeon @ Leftovers
Bold
EVs: 252 DEF 252 SpDef 4 HP OR 252 HP 252 SpDef 4 Def OR 252 HP 252 Def 4 SpDef.
Ability: Water Absorb
-Wish
-Surf
-Ice Beam
-[unsure. could breed for Yawn]

^ probably not my starter. All-purpose wall.

Lucario @ Wise Glasses
Timid
EVs: Unsure as of now
Ability: Inner Focus
-Aura Sphere
-Psychic
-Dark Pulse/Shadow Ball
-Calm Mind

^ Starter?

...and that's it. I have some things of interest though, and a few Pokemon I'd like to use but I'm not sure how.

Interesting/useful things:
-Totodile [Adamant] w/ Dragon Dance/Crunch/Thrash
-Feebas [Modest] w/ Mirror Coat
-Drifloon [Bold] w/ Minimize (Aftermath + Unburden)
-Swablu [Calm]
-Electrike [Timid]
-Croagunk [Jolly] (Anticipation)
-Pichu [Lax (bleh)] w/ Encore/Wish
-Aggron [Adamant] Lv50, Unknown EVs w/Earthquake/Roar/Stealth Rock/Iron Head
-Farfetch'd [Adamant]
-Togekiss [Timid] Lv30, Unknown EVs w/Aura Sphere/Air Slash/ExtreemeSpeed/Thunderwave
-Gyarados [Jolly] Lv30 Unknown EVs w/Stone Edge/Waterfall/Bite/Dragon Rage
-Jolteon [Timid] Lv50 Unknown EVs w/ Shadow Ball/Thunderwave/Hidden Power [Dunno what type yet]/Thunderbolt

...-_-; I'm very bad at choosing. I think I'll use the Jolteon if it has a good HP Type.
