i do have Application server and WFE servers....where exactly i need to deploy .wsp packages... from my understanding i need to installed in application server where central administration is running.....but how WFE will come to know that new packages is added to central administration site.................

With the release of SharePoint 2007 (MOSS 2007 and WSS v3), Microsoft changed the way that SharePoint Solution Packages (.WSP files) need to be deployed to a farm with multiple servers. Instead of copying and installing the package on each server in the farm individually, you add the solution package to the farm's central solution store once, then deploy it to each web application within the farm that needs to have its functionality for use. When you run those commands, SharePoint automatically creates timer jobs to run asynchronously and install the package's components to the correct uniform locations on each server in the farm without you having to do it yourself. So all you need to do is run STSADM's AddSolution operation to add the solution package to that central store, then run the DeploySolution operation (or deploy it via the Central Admin site), and SharePoint will take care of installing all of the package's bits according to its manifest file on each server in the farm. It doesn't matter if the server is an App server or a WFE, they'll all get the bits, in the event that you may need to change a server's roles down the road.
