comment How to join a WFS layer to a table in OpenLayers
I think you need to provide a little more detail. What is the data structure of the exported table? (JSON, HTML, etc) and then how exactly do you need to join the two? Do you want to click the feature on the map and show the data from the table? Do you want to click a row in the table and highlight the corresponding feature on the map?

comment How to calculate which zip code is closer to which in USA using C#?
When you say closest by zip code do you actually mean "five closest in the same zip code as the user?" Or do you simply mean the 5 nearest businesses? The distinction will be important in how the query you need is constructed! A ZIP code is an area of multiple addresses so you need more detail if you want the nearest, I.e. You need more specific location information like lat/longs - if you don't have these then you will need to first geocode all your business data.

comment How to calculate which zip code is closer to which in USA using C#?
Do you have the data loaded as spatial objects in the database? What database are you using? In this case whether the zip is valid is almost irrelevant - if you've been supplied the data then you can make the assumption that it is correct/valid! What is important is having the data in a form that you can perform a spatial query.

comment OpenLayers + GeoServer's WMS — Passing Feature ID into a Variable
This is the "right way" to do it. WMSGetFeatureInfo control was designed for exactly this purpose. By the way you can also create a free marker template in GeoServer to create a custom response from GetFeatureInfo requests if you don't want HTML table or GML - docs.geoserver.org/stable/en/user/tutorials/freemarker.html

comment Request data from OpenLayers to a standalone GeoWebCache
I think you are getting confused between geowebcache.xml and geowebcache-core-context.xml. The geowebcache.xml file contains the details GeoWebCache needs to give you the layer options. And geowebcache-core-context.xml allows you to specify the location of a WMS GetCapabilities document so that GeoWebCache can automatically configure layers for you from your WMS.
