Yes, it is safe to plant them. The entire plant contains those alkaloids, mostly in unfinished roots, and flowers or pods. But can be in some concentration in the leaves as well. They may take a little longer to seed, but they will be safe for you to plant.

It should be out of the soil long before they are ready to eat, but I would definitely not do this in the future. Depending on how close you do this to harvest, it could make them unsafe.

Most gardeners don't have to be that particular about the soil pH of their potato rows. You can raise good potatoes with a pH ranging from 6.0 to 6.5, the slightly acid condition that is still suitable for many vegetable crops. However, lower pH is better if you want greater yields and less disease. Commercial growers monitor their soil ph carefully to avoid scab in the crop.

If scab disfigures too much of your crop, you should try to reduce the soil pH. While scab doesn't look great, it won't cause your potatoes to rot or decay, so you may decide to accept a little on some potatoes rather than start tinkering with your soil's pH. It's okay to eat scabby potatoes; simply peel and cook them normally.

Yes, you will not need to be concerned with the potato's bloom cycle. This will be irrelevant to planting. Go ahead and plant as normal.
