Is there way to tell the bash find command to output what it is doing (verbose mode)?

For example for the command: find /media/1Tb/videos -maxdepth 1 -type d -mtime +7 -exec rm -rf {} \; to output:

Found /media/1Tb/videos/102, executing rm -rf /media/1Tb/videos/102
...

The unix find(1) utility is very useful allowing me to perform an action on many files that match certain specifications, e.g.

find /dump -type f -name '*.xml' -exec java -jar ProcessFile.jar {} \;

The above might run a script or tool over every XML file in a particular directory.

Let's say my script/program takes a lot of CPU time and I have 8 processors. It would be nice to process up to 8 files at a time.

GNU make allows for parallel job processing with the -j flag but find does not appear to have such functionality. Is there an alternative generic job-scheduling method of approaching this?

what is the default sorting order for entries returned by the linux find command?

For example, if I issue 

find . -type f -name '*mp3'

and the output consists of multiple files across multiple sub-folders, what is the default order in which directories are listed? At the same time, what is the sorting order in which files within an individual directory are listed?

Sometimes it returns:

./B/01.mp3
./A/01.mp3
./A/04.mp3
./A/02.mp3

See how first the contents of directory B is listed, then that of directory A. At the same time within directory A, files are listed in a funny order.

find has good support for finding files the more modified less than X days ago, but how can I use find to locate all files modified before a certain date?

I can't find anything in the find man page to do this, only to compare against another files time or to check for differences between created time and now. Is making a file with the desired time and comparing against that the only way to do this?
