I'm going to guess the TIFF doesn't have a world file, therefore the
extents will be the X-Y pixel values of the image (which are out of
the range of lat/lon).  If that's the case, you need to import the image
into an X-Y location and rectify it to your lat/lon coordinate system.

If it does have a world file, are you sure it's a lat/lon projection?
The last two numbers specify the coordinates at the center of the upper
left pixel.  Are they between 90 and -90, and 180 and -180,
respectively?

If you're referring to the startup, you can change the mapset to
whatever you want it to be.  There will always be a PERMANENT mapset,
when you create a location, regardless of whether you use it as the
active mapset or not.
