Brahms valzer op. 39 n. 14 fingering

[guiferra]

Can anybody please suggest me a possible fingering for the octaves I indicate with the red arrows in the enclosed score?
And more: the notes of the left hand indicated with a point (staccato) sound really different from other notes? All notes of the left hand are "non legato" and it gets quite difficult to make sound different notes signed with a dot than notes without it, when playing the valtzer at its high speed.
Thank for any advice.

5 on grace note, sliding down to 531 on the chord. When the notes move black key to white key (C# to B) it's not that hard and pretty safe. I'll see about making a quick video tomorrow since the baby's sleeping right now.

As for the staccatos, I'd probably interpret them as light accents.

Many thanks for your comments.
I actually tried the fingering you suggest and it works fine when the speed is low, but when I try to increase it (even far before arriving to its actual high speed, someone says metronome is 180 crochets!) the sound is not clear and the movement becomes clumsy.The fact that the distance from the grace note and the chord is a tone rather than a semitone complicates even the matter.
I suppose I have to practise it hundreds, thousands of times before I can play it at the corret speed...
Thanks!

Does anybody has any other solution for the passagge with the grace notes I asked in the first post.
Apart from the suggestions of lizt1022 I tried also this one:
5 on grace note c# and then 124, 134, 124 on subsequnt chords, but sometimes it make me plays strange notes, specially at high speed.
but I am not sure about which fingering is best and if there maybe another even better solution...

You could try 4 on the C, with 135 on the chord. Should work for the first and last, but not sure about the middle one.
