 VB4 to VB5 howto (a newbie)

Hi everyone,

 I recently made a career move from VFP to VB and my first project is to
migrate an in-house VB4 application onto a VB5 application.

The current application has the following specifications:

 Windows NT 4.0

App (All 16-bit)
 1. VB4
 2. Crystal Reports
 3. VBTools VBXs
 4. WINAPI calls
 5. Access 2.0 database
 6. Data access using Jet engine DAO 2.0
 7. Using secured database SystemDB (Access 2.0)

Goals - All 32-bit

My initial evaluations on the migrations including
 * Convert all crystal reports to 32-bit
 * Upgrade 16-bit VBTools VBXs to 32-bit OLETools
 * 16-bit WINAPI calls need to modified because of different variable types
in 32-bit    
 * Convert Access 2.0 to Access 7.0
 * Using Jet engine DAO 3.5 for data access
 * Convert secured database SystemDB to Access 7.0

My problems are:
* The clients using this application are in a different city and the
upgrade will be
   transferred via eletronic BBS instead of on-site migration.
* Anything that I need to be aware of on the Crystal report conversion?
* Where can I obtain OLETools and is the conversion going to be seamless?
* The Access 2.0 SystemDB is using an .INI file for security, but the
   SystemDB retrieves the information from the Windows registry instead of
   INI file. Is that true? How do I implement it by using WINAPI32 calls?
How do
   I update the registry to register the SystemDB and retrieve the info for
user login

Any ideas or suggestions will be highly appreciated and please direct your
