That link doesn't show a specific tool when I click it - but I generally 
agree that the Dremel should be fine, and any cylindrical grinding or 
cutting tool should be fine for your task #3.  I would also recommend a 
drill stand like Dremel's 220-01 WorkStation or this one from Milescraft 
<http://tinyurl.com/yqsasp> (which I have).

To remove ridges or embossing from a flat plastic surface:

1. Put Dremel in stand with cylindrical grinding tool.  Position 
workpiece under it.  Place two thick plastic bags (conductive bags from 
electronic parts orders, e.g.) underneath workpiece.

2. Pull the stand's handle all the way down.

3. Slide Dremel down the stand's shaft so the tool rests directly on the 
workpiece, in an area that has no embossing.  Clamp it there.

4. Release the stand's handle.

5. Remove one plastic bag.

Now you can start up the Dremel and pull the handle all the way down to 
get it precisely down to the level you want, less the thickness of the 
removed plastic bag (for clearance).  The plastic bag remaining protects 
the surface of the workpiece as you move it around on the drill stand's 
base.
