If you are using VisualGDB on a machine with no internet connection, then you can download the STM32 bsp from http://visualgdb.com/hwsupport/BSP/ and the arm toolchain from http://gnutoolchains.com/arm-eabi/ . The bsp should be installed in the embedded project wizard where usually the BSPs are downloaded for devices, but use the “Install a package from file” option there. The arm-eabi toolchain should be installed just from using the installer.
