DRV2605EVM-CT: What's header for J4?

Hi TI support

         I already purchased a DRV2605EVM-CT, installed CCS and dowload DRV2605EVM-CT Reva project source code.

         To proceed , I want to modify and reprogram Haptic effect in DRV2605EVM-CT. 

         In the "DRV2605L ERM and LRA Haptic Driver Evaluation Kit.pdf" page 24, I need to purchase a MSP-EXP430G2 and a header for J4 .

         So my questions are:

         (1) What's header for J4?

         (2) In your website, your MSP-EXP430G2 is out of stock, may I know when could it is available?

         (3) In the DRV2605EVM-CT board, I don't need to handle driver for DRV2605. However, I need it if I design DRV2605 in my PCB in the future.

               May I know where could I download the DRV2605 driver?
