I'm working on three MP-related things and have looked through these forums for the answers to what I'm sure must have been asked before but haven't had any luck. I am completely new to MP so if some kind person(s) could point me in the right direction(s) I would be grateful.

Scenario 1:
Using a client-side VBScript application (HTA) to search / display data from a MySQL database. -Are there any VBScript examples for MP2k4? -I can find some straight VB / EXE examples but have had no luck adapting them.

Scenario 2:
Using the process mentioned above, I need to find addresses within X miles of point Y. Do I need (or would it be faster) to have long/lat in the DB already?

Scenario 3:
Part of what I'm working on is web-based. In order to remain EULA compliant, I would like to be able to submit - from a web form - information to the locally installed MP. Having something (script or whatever) installed on the clients machine as a prerequisite is fully acceptable if necessary. -I'm mainly looking for possible approaches to explore on this one.

This is a very comprehensive forum and I'm very new to MapPoint - it's a bit overwhelming so thanks in advance for any direction or links!
