Very good advice, and really all you need to know, other than what each permission is used for and its implications. If you have any questions about application/permission mix by all means ask here.
Some appliction developers are remarkably lax on managing application permissions and accepting the users' decisions. I remember one update to Google maps asked for a rediculouse set of permissions and sent the device into a reboot-loop if it didn't get them. They changed their approach somewhat and are doing better, but not every developer is.
