Google Maps API w/Geocoder

I currently have a slightly modified Phoogle that I use to pring up multiple addresses on a google maps API. I have found that the [login to view URL] is lacking a LARGE amount of the addresses I need to look up. I now wish to use [login to view URL]'s SOAP interface to process the geocoding. As is stands, I use NUSoap PHP client to access the information. The largest problem I am facing is the authentication factor. All the necessary information for processing the login and such is on the [login to view URL] website for developers. There is no PHP example code, but you can probably look at the other example code to figure out the process. Ideally, I want to be able to pass addresses to a PHP page as such: [login to view URL] databank way, 30001&a1=1212 nameless way, 34666 etc etc.. Up to 9 variables. Any variables left blank need not be processed. Any output that does not geocode (comes up with zeros or no response) needs to not be process by the google maps API (or the mapping will fail). The map should automatically zoom out to show all points. Points should be marked as letters. Point 1 Should be marked 'A' on the map.. etc etc. (This part should be relatively easy. I was able to manage this part myself in a matter of minutes after reading the google maps API)
