On the first shot, I'd use 1:30 or so english and a lag stroke to go back and forth across the table, and the english should bring the CB back above the 9 to play it in the same pocket as the 8. It's a pretty wide margin of error, and I'd try not to hit the rail above the 9, but just lag close to it. My reason for that is in case I really over-spin the ball, the side pocket above the 9 could come into play, but not if I don't quite hit the ball hard enough to get all the way there.
On the second shot, it depends how easy the pockets are playing. If they're playing moderate to easy, I'd drop the english and hit the shot just above center, to come back below the 9 and play it into the upper right corner. On moderate to easy pockets I'm very confident on this shot, and it doesn't require me to work to spin the CB above the 9, bringing that side pocket I mentioned earlier into play. If the pockets are very tight, I might change my mind about taking the longer shot on the 9, and go for the spin shot to play the 9 in the same pocket. In this case, since I need to get further uptable and I'm scared of that cross-side scratch, I'd use more like 2:30 english, and try to get above the side pocket instead of between the 9 and the side pocket.
