I'm trying to get all the breedable hidden abilities. Unfortunately, I've reached the point where everything is either old events or Friend Safaris that I don't have. If anyone has anything off the following list that they could trade me, it'd be much appreciated.

Turtwig/Grotle/Torterra (Shell Armor)
Piplup/Prinplup/Empoleon (Defiant)
Pansage/Simisage (Overgrow)
Pansear/Simisear (Blaze)
Ferrothorn (Anticipation)
Litwick/Lampent/Chandelure (Infiltrator)
Fennekin/Braixen/Delphox (Magician)
Bunnelby/Diggersby (Huge Power)
Scatterbug/Spewpa/Vivillon (Friend Guard)
Litleo/Pyroar (Moxie)
Flabébé-Y/Floette-Y/Florges-Y (Symbiosis)
Flabébé-B/Floette-B/Florges-B (Symbiosis)
Skiddo/Gogoat (Grass Pelt)
Espurr/Meowstic (Own Tempo/Prankster/Competitive)
Swirlix/Slurpuff (Unburden)
Inkay/Malamar (Infiltrator)
Helioptile/Heliolisk (Solar Power)
Pumpkaboo-A/Gourgeist-A (Insomnia)

(Oh, and if you have a spare Lansat/Starf Berry or Sail Fossil floating around, that'd be appreciated too.)

If you're missing anything not on the above list, I can probably get one for you, so feel free to ask.

100%, the only moment when you can say that you've really finished a game. If you want more suggestions about games, why not playing the Devil Survivor games? The combat system isn't to different from FE, the difficulty is there if you don't grind like mad, there is several paths in order to finish the game ... giving them a try is worth it (though you also would have to look for some path guides too. Guide Dang It moments are the worst in any game).

I tried playing Lunatic once. It didn't end well. Who is your favourite character, by the way?

If you're looking for game suggestions, I recommend picking up Bravely Default. It's a JRPG à la Final Fantasy-- in fact, it's a Square Enix game. The characters, art design, and story are really good.
