Hi Caroline,
I'll answer what I can below. First though, it's highly recommended that
you place the .hluresfile in your home directory as is discussed here:
http://www.ncl.ucar.edu/Document/Graphics/hlures.shtml
That way your default font will be helvetica, amongst other changes.

You should set res@gsnLeftString = ""
By default, NCL will apply the long_name attribute from one of the
arrays input in the plotting routine and write it to the gsnLeftString
resource. In this case, I think it is taking the t@long_name attribute.
(Your t array is created from your v array, hence the v-component label.)

I am not sure what you are referring to here: The black outline of the
plot? (=perimeter). If so, try setting res@mpPerimOn = False

NCL has a png driver built into it, but it is not supported and we do
not recommend that you use it. Instead, it is recommended that you
create your png file by first creating a ps file, and then using convert
(convert -density 144 in.ps out.png) to create a png image. It is hoped
that png output will be fully supported upon the next release of NCL.
