Like TodFitch said, 1st and reverse aren't synchronized. I always quickly shift to 2nd then down to first (without releasing the clutch pedal) if I'm coming to a rolling stop, or even if I'm completely stopped. Keeps it from grinding. If already in 2nd gear I'll shift to neutral, then back to 2nd, then down to first. Any time I shift to reverse I'll quickly shift partially into 2nd, then reverse. As far as upshifting normally from 1st to 2nd to 3rd, after depressing the clutch I take my time shifting to the next gear, then it is smooth. If one hastily jams it into the next gear, it'll grind.
