You can if you want you don't have to. Rayquaza is a dragon type so if you hit it with ice moves like Kyogre or Walwrin it shouldn't be too hard, but you'll need lots of Ultra Balls and alot of patience and make sure that you save before you battle him just in case, but if you want to do it without trying to hard just use the master ball.
It depends. If u r catching it b4 the battle frontier, the save before u battle it, and use ultra balls.
If u r catching it after battle frontier, then go to the battle tower, give the item to a Pokemon u want to clone, put it in box 10, save, go to the link battles, do open battle, and when it is saving, turn it off. When u start it up again, u will have that Pokemon and it's item in ur party and in box 10. :)

You catch Raquaza in the Sky Pillar on the island near Pacifilog City.

No.
If you can't get in, then you can't get the MasterBall. Sorry!
save it for latios or latias, whitch is alot harder to catch than any other legendary. i caught all the regis and raquaza with ultraballs. see http://wiki.answers.com/Q/How_do_you_get_all_regies_in_pokemon_sapphire
masterball or 4pokeballs+3 greatballs+8ulatraballs the ninth ultraball will catch it
You can catch all of them, but if you're saying which one you should catch with a masterball, I would save it for Diagla or Palkia.
no
Well,the masterball should be used on what pokemon you think it is your favorite but the best choise for the masterball catch is the mighty lvl 70 MewTow how is a pain in the hole to catch with other pokeballs,but that is your choise
