Dave et al,
My setup is SnowPeak 700ml TI pot, TI wing stove, Esbit or Firelite tabs, windscreen.
I carry the stove, windscreen, and tabs outside of the pack in an exterior pocket. The pot does go in a stuff sack.
For me the residue is a serious inconvenience. I use sand, pine cones, grass, and whatever else to get the residure off the bottom of the pot before packing it. Crusty snow works best.
I've heard you should not handle the tabs do to toxicity and yet people don't seem to be bothered by the residue. It scares me and I do try to clean it off thoroughly.
At the altitudes and conditions at which I typically hike I do not get the boil times mentioned. In fact I rarely get a boil of 2 cups, I maybe get a few bubbles but that is good enough since I treat the water beforehand.
You can get the teeny esbit tabs from outfits that sell toy steam engines. Here is a sample URL: http://www.ministeam.com/acatalog/Wilesco_Kits.html
