If I have a set shuuter speed (ie sync at 1/125 sec) and the correct
aperature reads say F9 .
But I need a lower F stop to limit depth of field.
Will minus 3 stops of exposure control alow this and give me a 3 stop larger
aperature?
Also what would my F stop be here?
Are there any drawback to use exposure compensation. ( ie noise etc.).

Yes - that is what "stop" means -

I'm not sure, but you can just use either aperture or shutter priority AE
mode and run the other up or down and find out. If you are in shutter
priority mode, then increase shutter speed until you get the f-stop you
desire. If you go aperture priority, just set the aperture you desire, and
if there is enough range, the shutter speed will match.

You aren't talking about exposure compensation; you are just setting normal
exposure. There is no drawback to any set or range of exposure combinations.
Just the effects of high vs low aperture and high vs low shutter speed.

It sounds like you should only post your message once, and don't do so
much cross posting, it is considered bad manner. Some of the groups you
included have little to do with your digital camera.

You should be able to change the "film speed" on your camera. Lower it
to force a larger stop and less depth of field or raise it for more depth of
field. ND (neutral density) filters also work and they work on digitals.
 
Just keep in mind that one 'stop' worth of exposure time is a factor of
two, while one stop difference is a factor of about 1.4 (or 0.7), since
exposure goes as f/stop squared. That is, going from f/5.6 to f/8 is
one stop difference, and would take a doubling of exposure time.
