Your method of inserting the code is correct. To address your specific 
concerns:

  * putting the caption on the bottom requires the key/value pair
    "caption/pos/=b";
  * the label is not supposed to appear anywhere; it is used for
    cross-referencing the code elsewhere in the document;
  * the key/value pair to use the typewriter font family and color the
    code olive ("green" would be too hard to read, I think) would be
    "basicstyle={\color{olive}\ttfamily}".

You may need to load the xcolor package (or some alternative) explicitly 
in the preamble, if your LyX document does not already use colors elsewhere.

HTH,

Paul
