I would keep shared_buffers in the 10000->20000 range, as this is allocated *once* into shared memory, so only uses 80->160 Mb in *total*.
The lower sort_mem will help reduce memory pressure (as this is allocated for every backend connection) and this will help performance - *unless* you have lots of queries that need to sort large datasets. If so, then these will hammer your i/o subsystem, possibly canceling any gain from freeing up more memory. So there is a need to understand what sort of workload you have!
