Enable high or should i pulse the enable ?

You need to strobe the enable. Someone else has mentioned that you dont
need to use it if you use a timer, this is fine for small displays (up
to 16 chars for a 2mS timer) or if you can accept a short delay in
updating. If you need a fast update on a larger display, say if you
were editing text or monitoring real time data, you need to reduce the
timer to 50uS and use the busy flag with a character buffer.
