Do I have to use the RW if I am only writing to the display?

I am programming a 16x2 character LCD. I don't need to read the display, only to send information to it. So, do I have to connect to the R/W pin?

No. The R/W (Read/Write) is used if you are talking to and then requesting info from your display. If you are only writing to your display, then set the R/W to ground and move on.
