It depends on what you're doing. Guys cutting balsa for models use 1/16" bits. If you're cutting 3/4", then yes, use 1/4" minimum. Yes, you'll get lots of dust.
I cut a lot of curved work the way you're talking about, with multiple passes each offset from the previous. I've found with a round nose tool, very little sanding is required. With a square tool, a lot of sanding is required.
