[flexcoders] Basics question about FLEX 2 (newbie with flex )

[sshaders]

Hi all, 
I have two questions about flex:
 
I need to be compliant with flash player 7, 
can flex 2 compile AS2 code  target to player 7?

I'm using Remoting extension for flash MX 2004; 
can I use the same Remoting extension with flex 2?
Basicly i'm using AMFPHP, maybe there exist new connection string

in advance thanks 
best regard
