First, you have to defeat the Pokemon league 10 times.Then, this guy in the Pokemon center at the Pokemon league will ask you what your favorite color is, red or blue. If you pick red you get Latias and if you pick blue you get Latios.

you can do whatever you like just keep playing the game and there will be other events like the latios and latias event
you cant catch latias or latios in diamond/pearl. you can migrate latias and latios from emerald, ruby, sapphire. in case you dont know, you get latias/latios at the end of the game and the mother tells you what color(red-latias/blue-latios) the guy on tv says. the hard part is to find it. it randomly appears any where on hoenn.
Latios isn't in Pokémon Sapphire, but Latias is. Latias is in Pokémon Ruby! However, you can trade Latios from Pokémon Ruby to get it.
You must find AR codes for latios/latias are not wild in Diamond. I do not have an AR code for latios/latias. Sorry.
