Well if you already downloaded 10.5.6, the combo update won't help you any. The combo update that apple just released is 10.5.4, 10.5.5, and 10.5.6 all bundled into one, and since you already have 10.5.6 installed, this is not going to help you.

In my experience, combo updates can be more reliable & I resort to them if Software Update causes problems, which as I recall happened to me once, then the combo installer fixed it (a permissions issue).
For 10.5.6, Software Update did not cause any problems for me & sleep works fine.
