It probably won't give you an edge sales-wise, but...
It is always good to know someone on the inside. A manager is OK, but IMHO nothing beats knowing a techie or admin.
Talk to them with any questions you have, but make them good ones, nothing that will waste their time.
Be very polite and friendly - be a nice guy. People tend to remember this when you run into trouble and are more likely to help out.
All of this will pay out in the long run - but then, being a nice guy normally does.
