There's no need to use 1-3 in this piece, unless you can stretch it easily, you will use enough pedal for it not to have an audible effect. at speed it is very difficult to actually use 1-3 successfully. Plus you can find a perfectly acceptable fingering without 1-3. To learn this piece my advice would be to practice the outer sections slowly and staccato, but always slowly, trying to play them at speed all the time will injure you. As well as this don't forget the middle section. in my experinece the middle section is a lot harder to pull off than the outer ones.
