You never explain why you are running Mathematica on a cluster in batch
mode.  I could envision someone setting up a highly intensive numerical
calculation, for example, in Mathematica and then feeding it to batch
processing (although I have no experience in that kind of thing). But I
don't see why it would be necessary to work from the command line to do
this.

Mathematica is designed to work with the FrontEnd and notebook interface.
All the nice formatting, display of graphics, finding things, importing and
exporting, and operations such as DynamicModules are integral front end
functionality. If you want FrontEnd functionality you have to use the
FrontEnd, or program it yourself - which means you will probably never get
to the math. 

My suggestion is:

1) Get a good personal computer and work on that. They are not that
expensive. Forget the server.

2) If you have to use a server and batch processing because you absolutely
need processing power that is not available on a PC, then divide the work
into the portion that requires input, specification, formatting,  display
and presentation from that part that needs the intensive processing. Then
use the notebook interface to ship it off to the batch processor, wait for
the results and when they arrive manipulate them for presentation. I'm
fairly certain someone can show you how to do this.

3) If someone is forcing you to use Mathematica solely via the command line
interface but wants front end features then find some better situation. It
will be too frustrating. 

Unless you are in need of special augmented processing power, batch
processing is so 1960's era.

Sadly, If I am running mathematica on a cluster in batch jobs, connecting
over ssh I don't have much of a choice.  Sometimes I play around on the
frontend to get things working, but it doesn't do me much good if the output
of the batch process is not readable and full of \[...]
