Highly accessed as in frequently selected? You could probably track
that with Fine-Grained Auditing.
Otherwise, you'd be stuck with the LogMiner/ segment-level statistics
approaches, with all their limitations.

Define "most updated row". Do you mean the particular row that has been
affected by the largest number of UPDATE statements? Unless you are
tracking changes to the rows via triggers, Workspace Manager, or
something else, Oracle will not track this sort of information.
If you are looking at a particular timeframe that you have archived log
files for, you may be able to extract the information via LogMiner, but
that would be pretty arduous. If you are looking for hot blocks, 9i
collects segment-level I/O statistics (v$segstat). That's going to be a
large number of rows, and you can't differentiate UPDATE activity from
other types of activity, though.
