Hey guys. I've started learning beethoven's op.2 no.1, and since i'm self-taught, I thought I'd come here to ask a few questions. So if you have time and/or dabbled with this sonata, i'd be grateful for any help

Movement 1:
-in the development section, m.69-71, I'm having trouble playing the RH crotchets. for m.69, i use 1 and 2 for the F and Dnatural. and I play the B natural with 4, and then C natural with 5. then continue the tremolo with 1 and 2. I'm having trouble playing this at speed, and especially bringing out the two crotchets, since at that point my hand is stretched almost completely.
-in m. 71 it's even harder, since I have to transition between A natural and Bb, so i have to use 4 and 5 to maintain the slur. This is EXTREMELY awkward for me to play, especially at speed. Again, having trouble bringing out the 2 crotchets.
Apart from this movement 1 is pretty straight-forward. Fun to play. Gonna take a while to really ingrain the fine details.
Movement 3:
-Just a question about the trio section, where the RH plays double fourths. does anyone know a good fingering, and is it supposed to be ALL connected? I've managed to use a fingering but it certainly isn't ordinary, by any means.
Finally, Movement 4:
-Finding real trouble with the lightning speed arpeggios. Especially keeping them quiet and even (both in duration and dynamics). Any tips for this? Should i practice small sections fast, or at a comfortable speed and increase the speed gradually?
-Any tips on voicing the first note of each triplet (eg. m22-28 etc)? I'm practicing several things, such as playing the upper note and "ghosting/miming" the other 2. Or things like playing the upper notes legato+forte and other notes staccato+piano. Just wondering if you had any better suggestions.
-The 3 against 2 poly rhythms look like they're going to be really tough to pull off at the incredibly fast tempo. Any suggestions here? I can play them at a comfortable tempo, but they seem impossible to do accurately at prestissimo.
-Any practice suggestions on how to play the LH REALLY soft? I can play it pianissimo at a comfortable tempo, but again, when i play really fast the dynamic range diminishes substantially. So I'm open for suggestions, if you have any.
I know this is a HUGE post, but I really want to form a great finished product. I don't want to take shortcuts/etc, so I'm making sure I'm using the best methods possible for each case.
Thanks in advance,
Pover
