We have a driver for the MPU6050 in our SDK. You can find it in the folder "SDK_8.0.0_folder\components\drivers_ext\mpu6050". This driver helps you initiate, read and write registers to the MPU. You will, however, need to write your own code to use the MPU in way that suits you. You can also search this forum for help. There are a lot of people using the MPU6050.
What do you mean by changing the name of the BLE? The name in the advertising packet? There is a tutorial discussing advertising and names.
