1) When you do a corner alg you also swap a pair of edges and vice versa. Your next alg will swap them back but if there are an odd number of edges and an odd number of corners (they are either both odd or both even) then you are left a pair of each to fix that have not been swapped back.

How to practice 3bld?
I have a very low success rate - it's around 30%. But when I practice edges or corners it's around 90%. My memo is around 40 sec - 1 min. My solves are between 1:40 - 2:20. So how to practice 3bld?

Are your dnfs execution memo mistakes? If they're execution errors, do some sighted solves but do each target blindfolded. If they're memo errors, go slower with memo and slowly cut down.

Two questions

1) is it legal to memorize each piece of the puzzle, put on the blindfold, dissemble the puzzle, reassemble it correctly, and stop the timer? :p

2) What do you do when you have your last two corners oriented correctly but permuted wrong? I know that if that happens with edges you just shoot to both sides but corners have three sides.

From your second sentence I'm assuming you've said oriented and permuted the wrong way round. If the corners need to be twisted, then shoot to any sticker on the corner. Look at the colour of that sticker you shot to. Shoot to that colour on the same sticker. Here's an example:
scramble: y R U2 R' U' R U' R' L' U2 L U L' U L y'
so here, if we're using OP, we need to solve the UBR corner. First, we need to shoot to any sticker on that corner, for example BUR. The BUR sticker is same colour as our R face, so after that we need to shoot to RBU. So we would do:
[R' F: R U' R' U' R U R' F' R U R' U' R' F R]
[R2: R U' R' U' R U R' F' R U R' U' R' F R]

You can repeat this process for more corners if necessary.
You can also learn algs to twist two or more corners at once (e.g. the scramble I posted above and its inverse are easy to learn and very useful), but that's not necessary, unless you want to start getting faster.

Well. I've made few sighted solves after dnf to figure out, why I did dnf. I've slowed down with memo and execution and got 2/3 success rate, which is the highest I've ever got. And also got first mo3 and avg5 sub 2:00. It worked well.
