Unfortunately, the only means to breeding Abomasnow with Skull Bash in Gen V is by using a Squirtle, and the only means of getting one is by transferring or breeding then transferring the offspring of the Squirtle starter from FR/LG or the Squirtle starter given to you after beating Red at Mt. Silver by Professor Oak in HG/SS. Squirtle learns Skull Bash at Level 31, so keep it a Squirtle, or else it will have to learn it at a higher level if it evolves into Wartortle/Blastoise.
You are able to get a Ralts from either having Lena in White Forest or trading with Yancy/Curtis in Nimbasa City. Your best bet for getting both Shadow Sneak and Confuse Ray simultaneously is breeding Ralts with a Duskull, which you will unfortunately have to transfer over. Another alternative would be breeding a Litwick (Celestial Tower, Remembering Move) with Confuse Ray with a Ralts, then breeding the Ralts that knows Confuse Ray with a Bannette (Strange House, Remembering Move) who knows Shadow Sneak.
You can trade for a Togepi with Yancy/Curtis at Nimbasa City, or you can capture it while you have Miki in White Forest, if you're patient. You can also transfer or breed then transfer the offspring of the Togepi given to you by Prof Elm in HG/SS or the Togepi given to you by Cynthia in Platinum. Serene Grace is an ability that can be obtained normally. It is also one of the 2 abilities you could get from breeding a normal Togepi, so make sure the ability is Serene Grace instead of Hustle while looking for the perfect Togepi. You can breed a Plusle or Minun (Route 6, Swarm, Remembering Move) that knows Nasty Plot with the Togepi, then breeding the offspring with a Woobat (Victory Road, Cave, Remember Move) that knows Future Sight.
Growlithe can be easily caught in the Virbank Complex. To get Close Combat, breed it with a Zangoose (Route 11, Dark Grass, level it up to Lvl 47) that knows it. It also learns Crunch at level 39, so have it level up and learn Crunch before evolving it into Arcanine with a Fire Stone. Flash Fire is one of the two moves Growlithe can have under normal circumstances, so pay attention and make sure your desired Growlithe has Flash Fire rather than Intimidate.
You can catch an Eevee in the Castelia City Park, which can be entered through the Castelia Sewers. You can Breed an Eevee with Yawn by breeding an Eevee with a Camerupt (White 2, Reversal Mountain, Lvl 39) or a Munna. (Dreamyard, Remembering Move) Wish requires you to breed a Togetic that knows it with either a Skitty (Castelia City Park, White 2) or a Pikachu (Transfer) then breeding either the Pikachu or Skitty that knows Wish with the Eevee.
If you have any questions, feel free to ask!
