You can get the luxury ball in Leaf Green by going to Lost Cave (a Surfing distance away from Five Island). You must locate Lady Selphy. She will battle you with two lv. 49 Persian. After defeating her, she'll take you to her house, which was the empty house you passed by earlier. Go talk to her when you have the Pokemon she wants to see, and she'll give you a Luxury Ball.

A Smoke Ball is an in-battle effect item that allows certain escape from wild Pokemon. In FireRed/LeafGreen, Smoke Balls can be bought at the Celadon City Game Corner for 800 coins.
It is a special pokeball that has a catch rate between a pokeball's and a great ball's. If you catch a pokemon with a luxury ball, the pokemon will grow friendly to you much faster than normal. This is good because there are several pokemon that will only evolve if they like you a TON. Some of these are Munchlax, Togepi and Golbat
That item doesn't exist in that game. Only in the 4th gen Pokemon games you can get it.
Give a Pokemon in Pokemon Emerald, Sapphire, or Ruby a luxury ball to hold and trade to Fire Red. You can get extra luxury balls by winning a master rank contest after your Pokemon already has the ribbon. There is also one luxury ball in the abandoned ship, but you need dive. As far as I know, you cant get the luxery bal without tradeing with the other games I listed, or trade with someone who already has luxury balls. -BubbaJ
