1) Benefits. You didn't mentioned other options, but if you are talking about some custom server-side implementation, the benefits are numerous:

  1. It's easy to connect to web service from J2ME.
  2. Multiple connection sessions at one time.
  3. You can use web service from different applications and different technologies.
  4. No issues with authentication and authorization.
  5. You just call method from ws and in response you get easy-to-parse XML.

2) Web service - MySQL:

  1. You have to create a Tomcat or IIS web service.
  2. From web service code connect to MySQL, call a query and return the result.

For Tomcat and Java web service:
