No, you don't need to specify both options.
"-qt-sql-*" means SQL driver will be compiled directly into QtSql4.dll. The result is that it's always available, no matter whether an application wants it or not.
"-plugin-sql-*" means the driver will be built as a plugin and loaded on-demand, i.e. when an application requests it.
The latter approach obviously requires less system resources (unused libraries are not loaded) and allows more flexible installation/distribution variants.

You don't need to specify "-llibmysql" explicitly because it's automatically done by the MySQL driver project file.
What looks strange to me is that you extracted MySQL to one directory, but in configuration options specified another directory.
