You cant on Emerald, but i believe you can catch and transfer them from FireRed and LeafGreen.

you cant get to it unless you have a southern island pass which you could have got at a gamestop or eb games a couple months after the game came out you can get them anymore but you can get the card on ebay or a different website that sells things like that.

Sapphire gets Latias instead.

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.
the way to get to birth island is to get the auroua ticket

Latias is a legendary pokemon, so you cant get an egg from either latias or latios, even though they have genders.
