First I would suggest setting the /ONGLASS keyword for IDLgrText. From your
description I think this is what you are looking for. Check the docs for
details.
As for sizing the text so it fits on your screen you have a few options.
Setting the font explicitly to a smaller size via the FONT keyword, reducing
the text LOCATIONS Z value thus moving it away from the viewer (depends on
the IDLgrView PROJECTION setting), and adding the text to an instance of
IDLgrModel and then scaling/translating the text into position.
All of these options can be used alone or in combination and will move the
text around on your screen. I would probably put the text in a model then
scale and translate it into place. It might be a little convoluted but it
is easy :)
You may want to consider picking up Ronn Kling's "Power Graphics with IDL"
which is a great introduction to IDL's object graphics. His website is
www.kilvarock.com.

He is still around but I think the years have been hard on him. He talks
less and less about IDL and he rambles on about tennis, kids, marriage...
It should be a warning to all of us as to what IDL can do to you :o
But he still does have a great website wherein you will find many answers to
your object graphics questions. His website is www.dfanning.com.
Good luck!
