I thought this was a great tip too and as soon as I read it I set up 2 new taskbars. I now have 3 (top, left, bottom). The top one has my programs, the bottom has links to utilities (AV, spyware progs, control panel, my computer, etc) and the left one has the start button and running applications and the tray (where the little icons are).
I have auto hide turned on and the taskbar locked and "keep the tasbar on top of other windows" ticked. The taskbars pop up when I put the cursor near the edge of the screen.
(These screenshots show 2 taskbars on each, I can't get all 3 to show at the same time.)
As far as the size of the bar goes, right click on the main taskbar and click on "lock the taskbar" to remove the tick then grab the edge and drag it to whatever size you need. Go back and lock it again.
I don't know much about hotkeys but you might have to reassign a different key.
I do know that you have to have the folders you made to have the extra toolbars on the desktop all the time or it won't work. Mine are hidden under the "To Do" widget in the corner along with the recycle bin.
