Yep.  The defaults should be fine for this.

Trouble is, "a [little] bit more documentation" won't help at all.
You'd need a reasonably comprehensive document to give the user any
extra knowledge about how to tune ext3.

Ext3 does pretty much all the right things on its own by default ---
it was always intended that ext3 be as simple as possible an extension
to ext2, so users don't need to worry about too many tuning variables.

The down side is that tuning ext3 doesn't make any sense unless you
understand what it is doing, so any documentation that would introduce
those concepts would have to be more than just a small extra
description: it would have to include quite detailed descriptions of
the various things going on inside ext3, and the impact of all the
different journaling modes, to be of much use.
