Well the Chocobo Eater fight is easy if you're not trying to knock it off, but if you are, it's essentially using Tidus, Auron/Kimahri and Lulu, put Haste on everyone, Power Break the boss, cast Cheer, then spam Fire (I had Fira so it was easier) and melee attacks, and once it's your turn again, switch out to someone who has Sensor on their weapon (Kimahri usually does) and check the health of it, if it's low, throw it a Hi-Potion, just keep it alive while you're knocking it back, lol.
As for the Blitzball tournament, I've only ever won it twice, and I've finished the game over a dozen times, lol... but oh well, I don't really need the strength sphere yet anyway...
Right now I'm in Mushroom Rock Road just grinding right before the Sinspawn Gui fight, because it's the first boss of the game that ever gives me any grief, so I'll be grinding here for a while, atleast until Kimahri and Auron can hit 800+ off with their normal attacks (At the moment they're hitting 400-600 with normal, but Kimahri seems to crit a lot and hits 1,100-ish) to get rid of Sinspawn Gui's arms and get on with hitting the body (Lulu can hit 1,300-ish with her -a attacks, so I reckon she'll be fine with solo'ing the head, although Wakka could help too, but damn he's pretty weak at the moment, I'm not a fan of using him, he only has 18 STR, lol)
