you cannot ever beat the battle tower. but if you have completed the sinnoh pokedex then the battle tower will help you complete it. you can battle at the battle tower as long as you want.
There are many hidden quests after you defeat the Pokemon league. like catching rayquaza, getting the regis, Battle Tower (Battle Frontier in Emerald) Battle steven in Meteor Falls, Catching latios, going to moon , etc
Okay, to get the Pokemon to fill the National Pokedex, either you: migrate Pokemon from Emerald, Ruby, Sapphire, Firered, and Leafgreen. Or you could go in the wild near thesurvival area, which won't help a lot but it can help. Hope this helps!!
TO get symbols you will need to defeat the leader of each battle places on the island because i already have them all. well hope this helped! bye and also try to find useful items in battle areas that my help when u fight them bye-bye From:kate the great
