Wider tyres may help, the main advantage is better protection of the rim when you ride into a pothole full of water. Some frames take wider tyres OR fenders, in which case, i would go for full-length fenders, bolt-on style if you have the eyelets.
This. When I ride long downhills I tend to alternate front rear feathering so one wheel is controlling my speed at all times. I do the same in rain but tend to keep my speed lower than in dry conditions.
