My tomato plants, "Early Girl" "Jet Star" and "Beef Steak" are planted in containers and growing an inch or 2 a day. Now they are reaching a height where I will need to prune them to manage any more reach. Is there a trick as to where to cut them back, or does it matter. All have many blossoms set and seem to be starting more all the time.

Tomatoes grow tall when they have support and they are well cared for. Consider it a compliment that they grew so well. You can limit how tall they grow by limiting the support system you have. Once the plant folds over, it signals it to stop growing up. Suckers can produce flowers the same as main branches.
If you decide to prune, use a very clean pair of shears and cut at the place where the branch you are trimming meets the stem. Allow it to air dry and do not water the foliage of the plant for a day after you prune. Whether you remove the suckers is a personal choice.
