Liszt - Sonata B minor (learning notes)

I use Peters Edition.

So far I've "learned" nine pages of this work. By "learned" I mean they are half memorized in middle tempo. They wasn't so hard as I expected.

First page is all about proper mood and rhythm. I use 3-2-1 for sixteens triplets, so they are not a problem to sound light and sharp. I don't worry about thumb on a black key ;).

Passages on the second page aren't so hard too, fluent hand movements are needed but that's all.

At the third page I'm still not sure about fingering, I don't like to use 5-4-3-2-1 fingerings (first group in right hand).

At fourth page there are some triplets, which need more attention. I use 1-2-3 in right hand for them and 3-2-1 in left hand. I think it's better fingering than indicated in the score. Thumb in right hand needs to be fast to get to the octave, but it's easy to have proper clarity and energy. The thumb needs to be really relaxed.
In left hand the 3-2-1 works good, the passage after this triplet it's easier when started from the second finger (2-1-2-4-5 1-2-4-5) because there is one position instead of two.

I was thinking a lot about fingering in right hand in those bars. I decided to start passage (beginning of each bar) from the second finger, so it's 2-1-2-4-5-1-2-3 5-4-2-1-2-1-2-4-5. There is one problem in that fingering, from 5th finger in last sixteen I need to get to the second finger and the interval between them is sixths, which is a little stretchy for me.

Octaves. I like octaves, but there are some jumps in these (especially I don't like 7ths jumps). Pattern is easy. I practice in a few ways:

1. only thumb in right hand
2. only pinky in right hand
3. only thumb in left hand
4. only pinky in left hand
5. thumbs in both hands
6. pinky in both hands

In this kind of octave passages I try to always use pinky on top note, because it's just less thinking about fingering.

This one seems easy, but chords in left hand contains some repeated notes from part of right hand, so this spot needs some attention.

In this spot I can't still decide which notes I should play by right hand, only melody or use a little help in accompaniament too?

 From the third bar in this picture starts some hard section. It needs to be light, pianissimo, but intervals are quite wide. I use thumb instead of the second finger in this figuration - the second finger plays only last note in each group. I'll see if it will be good.
