committing changes

[Dan 'Da Man']

Now that I have been so graciously granted the ability to commit
changes, I have some questions regarding the exact methods to commit
changes.  First, does committing changes differ greatly than how I
have already been committing changes?  Second, if I find something
that needs to be changed, should I file a bug before making and
committing the fix to the bug?  Third, after making the changes/fixes,
should I push the commits to my own branch (lp:~heymrdjd/...) before
committing to the trunk.  Fourth, does committing to the trunk make
actual changes to the (x/k/edu)ubuntu-docs package?
