There are two symbols I do not recognise below the stretto in this excerpt:
What are these symbols? And also, form what I read the stretto here should be interpreted as an accelerando, am I correct?

I wouldn't interpret stretto as accelerando. My guess is that Chopin put it there to prevent the other natural interpretation of the passage, which is to slow down, from happening. So, instead of doing an accelerando, the passage under the dashes should just be generally faster/flowing, probably slowing down during the last hairpin (>). You'll need to experiment to find a natural way to do it.
