A good place to start are the following sections from the Mathematica 
Book 5th Edition:

"2.13.9 Two-Way Communication with External Programs"
http://documents.wolfram.com/mathematica/book/section-2.13.9

"2.13.12 Manipulating Expressions in External Programs"
ttp://documents.wolfram.com/mathematica/book/section-2.13.12

"2.13.14 Running Mathematica from Within an External Program"
http://documents.wolfram.com/mathematica/book/section-2.13.14
