Now, I only know a few blind people, but usually they don't ask things like this. They either know that they can do a thing or not. I'm not sure any of us can answer your questions well, as I have no idea what you can and cannot do.
Packing a pipe is about the "feel" anyways,
as philobeddoe has said. You learn to feel the pressure your assert, and then check it by drawing on the stem. If it feels like you are sucking on a straw of a milkshake, it is too tight. If it is unrestrained, it is too loosely packed. It should feel like you are drawing on a straw with a cola, just a little resistance. This probably makes more sense to a blind person than the rest of us.
As for lighting... have you lit a cigar? You just have to learn to know when it is lit enough for your preferences. Me, I never light the entire surface, because I smoke mine on the verge of going out to get the most flavor. The wider the cherry of fire is in the bowl, the less flavor you have, so I like to just get it going and then maintain that with slow smoking. As for how you should do it... you'll just have to learn what you like and don"t like.
When you suck a little ash in your mouth the bowl is cashed. Ha ha. I would think that the hardest part will be in knowing whether the bowl is still going at all. Sometimes, even though the fire is out, I still get flavor from the bowl. Maybe, this is a good thing for the blind. A bowl will last a lot longer.
As far as tobacco suggestions... what do you like, or expect? Do you want aroma-y aromatics, naturally sweet tobacco flavors, or campfire burning tires body odor latakias? :
