It can get uncomfortable, but it highly depends on how the seas are hitting you. Normally, it's meals and trying to sleep that become a problem. The ship is always moving, so a little added motion isn't bad. The worst seas are on the beam and quartering (on the side and coming from 45 degrees off dead astern, respectively).
But if it's really bad, the ship will alter course and slow down to minimize the motion.
Plenty of different jobs to go around. When we're not on watch, the deck officers will be correcting charts, doing safety inspections, and preparing for cargo onload/offload. Engineers will be fixing things that periodically break and doing maintenance items that don't require the main engine to stop. There are a lot of redundant systems which facilitate this.
Free time varies, but a lot a people try to work 12 hour days, so that's not a lot of time, until you realize there's nothing to do, then it can seem like an eternity. People usually either use the gym, watch movies, or play on their computers.
