Phantasma

So a few friends and myself decided that we wanted to start a superhero rpg and I am to be the GM. I came across Champions Complete and felt that this would be a good game to play, and then I started reading. I'm having a lot of trouble understanding and grasping the game, I don't know where to begin with the questions. 
 
Character Creation - I understand that a person is given an x amount of CP,  and everything is bought using them, but beyond that I'm lost. Building Attacks - There is no limitation to the kinds of attacks you can make, but the vastness of it confuses me. For example, if I was creating a character like The Flash how would I make a "Lightning Toss" attack? Combat - So based on the character's speed (Base is 2), that's how often they go in a turn and a turn consists of 12 segments. Is there a limit to what you can do during your phase? For example, in DnD you can make 1 move action and 1 attack action along with a bonus action and a free action, but not two moves along with an attack action and a bonus and free action. Is it similar here?  
Any and all help is much appreciated. I'm sure my questions have been asked before and they'll be asked again so apologies! If having a reference for a hero helps, a player wants to be a speedster similar to The Flash. In you explanation if you could use a speedster that would be extremely helpful (the starting CP for my characters is 300 and 60 for complications).

My apologies for taking so long to respond to your question — real life snuck up on me and got in a Surprise attacking, Knocking me Out for several Segments until I could recover.
 
1. That’s an error on my part; AquaChimp has to have Variable Effect too, as discussed in the main text. I’ll note that in the errata. Thanx for the catch!
 
2.  This is a classic example of me being a damned idiot. I accidentally gave the new Advantage on APG 55 the same name as the Advantage on 6E1 362, thus confusing you. Change the name of the new Advantage on APG 55 to Varying Special Effects to avoid this. Another one for the errata page. ::sigh::
 
3. Sure — Varying Special Effects is an Advantage for Adjustment Powers, and Suppress is an Adjustment Power.

My apologies for taking so long to respond to questions — real life snuck up on me and got in a Surprise attacking, Knocking me Out for several Segments until I could recover.  I can't promise it won't happen again, but I'll try to Dive For Cover next time.
