It's a while since I had pad/dribble issues but in the early days...
1 - kind of tuck it into the folded-down cup, and then rearrange it when clipping bra back up.
2 - I didn't dribble that much, but a muslin tucked under boob/baby face took care of most drips.
3 - forget about being in public as much as you can (easier said than done I know), if you're anxious you're likely to faff more .
Priority - don't drop baby or spray too much milk on it, get baby back on breast if it wants to, stem the spray and then worry about exposure.
Good luck! If you're struggling to feed in public comfortably, find a few places that are less stressful while you practice the bra strap shuffle.
