:] Glad I can help thus far.
You can EV train from whichever way you wish. I personally enjoy training from an egg (and as the pokemon is level 1 upon hatching, the only method of EV training I can think of before it can start doing battles itself is through medicines and EXP. Share).
Getting a good nature on your pokemon can be done in multiple ways. For one, a pokemon with they ability "Synchronize" can increase the chances of encountering a wild pokemon with the same nature as your Synchronize pokemon (or Sync for short). Say you have a Munna with Timid nature, if you search for wild pokemon with Munna as your leading pokemon, Timid nature pokemon will appear more frequently than they would normally. Or you could just keep trying to catch pokemon until you find the nature you want. Same goes for breeding. There's a method of increasing nature chances with an Everstone, but I forget which parent needs to hold it. I believe the female must have the desired nature and be holding an Everstone to increase the chances (don't quote me on that however).
Abilities are the same deal, minus the Sync and Everstone methods. Just keep trying until you get what you want.
Eggs moves are a bit different. Try searching a pokemon on
Serebii, and then scrolling down to the section where it says "Egg Moves". Next to each move should be a "details" section which will tell you which parent the pokemon would need to be bred with to produce a baby with that egg move.
