Questions:
1. If the super rich don't get taxed as much, do they really reinvest their money and help drive the economy? AKA the trickle down effect?
		
		
	 
No they don't.  We've tried trickle-down economics (or voodoo economics as Bush called it) and it's never worked.  
The more money that passes the most amount of hands is the most helpful to the economy.  i.e. If I have a dollar and then buy a sandwich from Joe, Joe then uses that dollar to buy bread from Paul, Paul uses that dollar to buy a widget from Sarah, and then Sara uses that dollar to buy my time helping her make widgets, then I use that dollar to buy a sandwich...  
Ideally that's best for the economy.  
Now let's pretend that Paul decides to start saving some of his Sandwich money.  Now I pay Joe a dollar for a sandwich, Joe pockets $.50 and buys half as much bread at $.50, Paul now only has $.50 to buy widgets, buys less widgets from Sarah, who can't afford to pay me as much.  Taking half the money away really hurt our economy.  Of course the money isn't really gone, Paul still has that $.50 cents, but for the economy those $.50 savings are gone.  
So giving someone money that they don't spend does nothing to the economy.  It's spending the money that makes things work, and people that are already rich tend to not spend the money they have, let alone any extra money they get.  
Again, this isn't to say saving is bad for you, personally.  Maybe Paul is saving money because he wants to take a day off to celebrate his birthday, so for him saving was tremendously helpful.  But for the economy of our small island it was disastrous.  
	
	
		
		
			2. Is it really better for the overall economy to tax corporations more?
		
		
	 
Wrong question.  This is like asking if it's better for your health to drink more\less juice.  The correct answer is it depends.  
Let's say I live in an island have a a seashell selling corporation.  I don't want bandits to destroy my seashells, so its in my best interest to have a tax for police to protect my shells.  Let's pretend that people want to make a bridge to the island.  Now more tourists can come visit me and I'm able to sell more seashells.  It's in my best interest to pay the tax for a bridge so more people buy my shells.  Let's pretend that for some reason the bridge is more expensive then everyone thought it'd be, either because of stupidity, corruption, nepotism, etc.  Now taxes are raised so high that even though I'm selling more shells then ever before, due to taxes I'm making less money.  
It really depends on what services are being provided, how they help society and whether or not they're worth the expenses.  
The non-corrupt Police are EXTREMELY helpful to any business.  If you don't believe me try and start a business in Congo or Zaire and see how well you do.  At the same time if there was a 100% tax on business to pay for the Police then businesses wouldn't exist.  
	
	
		
		
			3. Does more money in the pockets of the super rich help the overall economy more or money in the middle class folks?
		
		
	 
Economy-wise, it's better for people to spend all their money, as each dollar spent re-invigorates the economy.  
Thus money in the hands of poor people helps the economy the most, then Middle income, then Rich people.  Poor people tend to spend all their money, Rich people tend to save most of their money. Middle class income saves and spends.  
Again, I'm not bad-mouthing savings for you, personally.  The more money YOU have saved, the better YOU are.  But for the economy, each dollar saved is a dollar that's not being spent.
