Do you have Deoxys? If not, explore the Holy Karst Cave (east of Tyron Tower) using Waterfall. Find a meteorite, and after speaking to it, Deoxys will appear in a cave in the High Path (east of Redwood City). And Suicune? It's found at the Pure Tower, at Pure Village.
About the gym, you won't enter there, I think the trainer you find at the Abandoned Ship is actually the Poison leader.
Also, 1158, can you give a hint about that sword?, because I'm getting crazy looking at the caves, and I don't find anything...
