It sounds like the ML405 board. www.xilinx.com is where I would look first
for sample code and tutorials. You'll find there as many application notes
and documents as you would care to read. The memory manufacturers' websites
will also have vitally useful information.

With that said, I think it's way too much all at once to tackle as a first
effort. If you care to, back up a few steps, tell us what you're doing and
why, and what your expectations are. If it's a school project, stick with
their program, of course. But, if you're on your own, maybe someone here can
suggest a more reasonable progression to get you rolling. It won't be a
short journey, but you might find it more satisfying and worthwhile than
immediate gratification on your near term goal.
