The floaters are no good so pour them off with the liquid again leaving just the sunken ones at the bottom. Keep filling the vessel with water and pouring it off once they settle until the water is clear when you're pouring it off. Half a dozen times is usually good in my experience. Once done, just pour them into a strainer and put on paper towel till dried. Kept dry and properly labeled they should be good for several seasons.
* As for saving specific seeds, it's best to choose one of the earliest fruit or the furthest away if you want to maintain a specific variety. Tomatoes tend to get more cross-pollinated as the season goes on so getting early before things get messy is best in that regard. It's not foolproof unless you go to great lengths but there's a much better chance of getting what you want. Also make sure the tomato you save seeds from is a good representation of that type. So if you're saving from a brandywine and you have a big juicy perfect one versus a small weird one, take the former. It might seem obvious, but it really does make a big impact. All that said, random seeds are fun too and every year I'm delighted by the strange volunteers that show up.
