Yes, you should have a "pro" look at your particular installation.
This particular one you talked to probably is not a "pro".

It seems he likes to make sure you _understand_ how complicated
his job is, and how big a dope you are because you can never
hope to comprehend this material; I run into these types at Radio
Shack sometimes. 

Try to find a no-nonsense place to look at your installation, who'll
put it to you in very simple terms (yes, it is possible) rather than
dazzle you with BS.

(listen to me -- I sound like I've lost my patience :-)
