You asked:

Yes, look at the "cached" and "buffers" lines in your posting above.
Those two total to  around 235-240 megabytes.

This is NORMAL. Linux does this ON PURPOSE. you've got all that RAM sitting
there that would otherwise be DOING NOTHING, so the kernel puts it to use
providing perfomance-enhancing buffering and caching. These things can be
quickly freed if necessary, in case some program suddenly demands additional
RAM, so it's not like it's a problem.
