The fingering should be what you feel comfortable with, but I find it easier to go middle, index, ring. You don't really need to use your pinky because it will cause your fingers to become smashed together. Since it's so high on the fretboard. If it's lower, it would probably b best to use your pinky as you would normally.
It's very easy to play this part fast with this pattern. You pretty much sweep the first 2 downstrokes, then come back up with the upstroke. Also, with this being a triplet rhythm to a classical type piece. The last note is usually the more suspended (not noticably, but if you understand how triplets are broken up..it's not exactly even.) of the three. Even in some expressive classical music, the last beat before the next measure is usually suspended. Like the music will be at 108 bpm, and the last beat in the measure will be 92 bpm, then it will repeat that again. Probably didn't need to write that but it's something to know.
