Not really. Sell them, or give them to Pokemon to hold.

No. But don't give up, you can still get resharim in Pokemon white. It's simple. all you need to do is get a really, really, good Pokemon, like a level 100 haxarous with an item such as a master ball or a focus sash as a hold item. find someone with Pokemon black, and trade the really, really, good Pokemon. sadly you might permanentely lose it, but if you want resharim, it will be worth it!

you need a prism scale Feebas has to hold it then it will evolve
A pokeball that catch's any Pokemon (never misses) and can catch and hold multiple Pokemon found in Black and white.
You don't need them for the storyline, you get them so your pokemon can hold them and raise their stats.

It's like you've never watched pokemon!! Or never even seen it - you can only ever hold 6 pokemon.
You can't find it in the game. You can only get it at special Pokemon events. They don't hold them for Diamond anymore considering Black and White is now out.
You can use the Poketransfer which allows you to transfer Event-Only Pokemon to Black and White. Here are some notes you may want to know before and during trading:You can only trade event Pokemon (Entei, Suicune, Raikou or Celebi) using the Poketransfer (beginning of game) from Pokemon Diamond, Pearl, Platinum, Heartgold or SoulsilverThe Pokemon traded can not know any HM MovesThe Pokemon traded can not hold any itemsAfter completing your Pokemon Black or White Game, you can transfer other Pokemon from other generations, but you can not transfer Pokemon from Black and White to games such as Pokemon Diamond, Heartgold, etc.NOTE: Once a Pokemon is traded to Black or White, it can not be traded back, so choose wisely!

no unless in another white or black version someone gives it to their Pokemon to hold then trade it to you that's the only way to get another.
6 like all the Pokemon games!
