I don't think it's entirely the steam from too moist tobacco that causes "bite".
Some Virginia blends are notorious for this, and dont' change until they've 'aged' for awhile.
The packing sequence is good advice. Once packed, the pipe should draw as though you were sipping a drink through a straw: a little resistance, but not enough to make your cheeks cave in, or so little that it feels like the pipe's empty. Then, different cuts require different techniques. Cube cut, for example, is best smoked a little loose, as any packing will make it harder to draw.
A tight pakc will cause you to either draw harder, thus making the burn hotter, or puff more rapidly to keep it burning, with the same result.
Practice, slow down, sit back, relax, and enjoy.
As for Zippo lighters, the pipe insert works really well, although I still prefer a wooden match for the charring light. Better yet, if you can afford a Corona Old Boy, or find one on eBay, these are the ideal, IMO. And NEVER use a torch lighter!! unless you like the look of a charred rim.
