If your pokemon will compete at level 50, does it matter if your IVs are 30 or 31?
(Battle Frontier question.)
Yes, it affects the number of EVs you need to spend to bump them up one stat point. An IV of 30 doesn't matter in stats you don't plan to EV, but if you do want to EV a particular stat, an IV of 31 lets you save 4 EVs, or to get the full 17-point boost from putting in 252 EVs (best you can do with an IV of 30 is to gain 16 stat points with 248 EVs).
What order should I follow?
-Training EVs
-Evolve with Stones (or natural means)
-Give Proteins, Zinc, etc.
-Teach moves
Vitamins (Protein, Zinc, etc.) give EVs, so you should use them as part of your EV training. In order to work correctly, they have to be given before EV training via fainting things.
When you should teach moves varies. Egg moves obviously have to come before anything else; level-up moves should be taught when the Pokémon naturally hits the required level (whether before, after, or during EV training) if it passes the level in the course of doing other things, or after EV training if you need to level it up to the level in question just for the move. TMs can be given any time; give them early if you need the move to help you EV train (e.g. the Pokémon you're training can't OHKO a Starly or Bidoof without them), or otherwise wait until just before evolution, or even after evolution if the TM works on both the unevolved and evolved Pokémon, in case you change your mind about the moveset. Evolution should normally come after all move-teaching, unless you need to evolve the Pokémon to learn the move, because many moves become impossible to teach to a Pokémon after it's evolved (e.g. you want to repeatedly cancel the evolution of a Shroomish until it's levelled up enough to learn Spore, because Breloom has no way to learn Spore unless it knew it as a Shroomish).
How do you use the Export to Text option on the Team Builder in shoddy battle? I click OK but nothing happens.
Copy-and-paste the team into a program like Notepad (or the equivalent on other operating systems).
