As for scaling, remember that 1 foot is 12 inches. For 1"=20', the actual scale is 1 to 240. Look into scale lists.
If you have a printer and it can handle 8 1/2 x 11, you could print two halves of your drawing. If your print preview looks okay, though, the print should be okay.
As for title blocks, some people put them in paper space, some in model space. I prefer paper space, because that reduces clutter around the model and sometimes there are multiple layouts.
