The way I have solved this in TextMate is to record a macro that is  
triggered only when inside a math environment, and is bound to the $  
key. This macro uses a simple search to move the caret outside the  
math environment. So with this addition, whenever I want to start a  
math environment I press $ (and \( ... \) is inserted), and whenever  
I want to get out of any kind of math environment, I press $ again.  
(And of course the interior of math environments is colored different  
from everything else, in user-defined colors).

Would something similar be possible in TeXShop?

For the $$ stuff, I have another command that, when ctrl-[ is  
pressed, inserts:

\[
     [caret here]
\]

and another single keystroke converts any such equation to:

\begin{equation}
	[the equation stuff]
	\label{eqn:[caret here]}
\end{equation}
