Hmm. This implies features not sent or they are malformed and not parsed 
correctly. By way, I strongly recommend that you get used to the 
debugging with firebug or chrome tools. Makes investigating this much 
easier and you will learn a lot about OL in the process.
On the Net tab of either tool, you will see the POST request that 
fetches the features. Look at the response.  Is this the GML features 
that you posted earlier? Looks valid GML, except that you are requesting 
lineStrings, but I only see one point in each feature? Wonder if that is 
set up properly at the server end?

Well normally you would be wanting to access features in response to 
something that a user does (eg click on the feature - though if you are 
using WFS instead of WMS, perhaps you want hover?). This is usually 
managed in OL by controls of various sorts, each of which have events 
associated with them. You register a handler for the event and you get 
the features in context.
