This should be a FAQ question; it pops up way too regularly.

In a word, no.  What that says is that 3064 (Kb) has not been used by 
anything yet (has not been allocated).  But you have 356124 (Kb) that
has been allocated at some time but is now free (buffer/cache line).
And you have 1210536 (Kb) in available swap space.  So, you have 
350 Mb of "real" memory free for programs/data at the moment, and 
over 1 Gb of virtual memory free.  You should read up on memory use
by Linux - allocation, deallocation, how these affect reporting by
'free', etc.
