Check the size of you mail folders. Some distributions email you with
their log files every so often, and that can produce a lot of junk in
your mail. Browsing through a number of large folders can certainly
use up a LOT of memory, depending on the browser.

That is expected. Once something has been swapped out to disk, it
will never be paged in again unless it is actually needed. A lot of
your system binaries do things at startup which they never refer to
again, so yes, it's not at all uncommon to have 2M of permanently
swapped data.
