You can set the DPI in the Import>File dialog box regardless of whether you let Frame create the anchored or do it yourself. Personally, I prefer to insert my own, but YMMV. 

The thing is, to answer another of Brian's original questions, you can also scale an imported graphic proportionally by choosing Graphics>Scale.. and specifying a percentage (it's an overall percentage, not separate ones for horizontal and vertical). You can also scale a graphic visually by selecting it, holding <Shift>, and dragging a corner handle (if you do this *without* holding <Shift>, you'll resize the two dimensions independently). I find either of these methods more intuitive than adjusting DPI. 

Brian, as for Question 3 in your note, the anchored frame controls the position of the graphic relative to the anchoring point. Go into the Special>Anchored Frame.. dialog to tinker with the settings: You can have it float, go to the bottom or top of a page or column, run into a paragraph (if it's narrower than the column width), or a variety of other options. 

Hope this helps...
