free -m will give you the values in Mb which might be usefull.
Buffers and cache, are used by Linux to keep things efficent, but may have nothing in them that you can't lose, so you can usually deduct that from the actual memory used. The Cache and buffers, will decrease as other things demand memory.
You haven't touched swap, so obviously your doing nothing that demands more memory than you have.
Buffers: are used for accessing things, like disks and networks.
Cache: things you've recently accessed or might potentially access, so Linux won't have to go get them of the disk again.
