Our roma tomatoes have prolific growth. Is this a normal growth pattern? Do they need heavy pruning?
You can prune, but it is a personal choice as to whether you do it. This article will explain more: https://www.gardeningknowhow.com/edible/vegetables/tomato/should-you-prune-tomato-plants.htm
They do not need pruning. Keep them off the ground by simply supporting them with tomato stands (should have been put on when planted), or you can use a 4' tall roll of large diameter chicken wire from Home Depot, making a ring around the plant, if you have no other support in place.
You may need to hammer stakes into the ground up against and tied to the support cage to keep it from falling over from it's own weight. The plants get large and somewhat heavy, especially while they establish fruit. Use planting ties to tie the branches to the cage. Then get ready to start canning tomato sauce! Roma's are the primary tomatoes used in sauces for their great flavor!
Do you nip out the side shoots of ROMA tomatoes the same as you do for other tomatoes?
The answer to your question is yes you can but it's really optional. The decision to prune is a controversial one it seems. There are those that say it should not be done on bushy tomato varieties such as roma as it will reduce tomato yields. Then there are those (http://backyardgenie.com/delicious-roma-tomatoes/week-12-cutting-sucker-branches-from-roma-tomato-plants/) that say it should be done because those side shoots draw away nutrients from your developing tomatoes. It all depends on what your school of thought is on this. You can try pruning some and not others and compare/contrast the quality and quantity of the yields which will help guide you in future plantings.

The leaves on my roma tomatoes are curled up. The other tomatoes look normal. The romas have fruit on and are blooming. I water every other day.
There are several reasons this could be happening. The most likely and harmless is temperature fluctuations. This article can give you some other possibilities:

Is it possible to grow Roma tomatoes in a planter (on a very sunny deck area) or do they need to be in a garden type environment?
Yes, you can. This article should help: https://www.gardeningknowhow.com/edible/vegetables/tomato/growing-tomatoes-pots-containers.htm
I am growing Roma Tomatoes in a garden box and have been watering them since it's getting pretty hot here in NC. But they are growing very small. One was ripe but looked like a golf ball size cherry tomato before it started to rot. Do I need to add more fertilizer within the soil than what I used?
Water is very much a part of tomato success, but good rich soil, adequate container size, full sunshine, a good organic fertilizer are all important. Don't over fertilize, this will cause all plant and no fruit. Follow package instructions.
I have great success adding Epsom Salt to all my tomato plants as soon as they are blossoming.
I would add about 1/8 cup sprinkled around the base of the plant and watered in each week.

Our Roma tomatoes planted in containers are doing well except we just noticed the tomatoes are turning brown at the bottom (not the stem end) before they ripen. Can you explain why? Thanks in advance--my grandchildren are feeling sad for their plants.
This is blossom end rot. This article will help:

Why do I have brown on the bottom of the Roma tomatoes in my garden? The tomato fruit is still green but the bottom of he fruit is brown.
This is Tomato Blossom End Rot.
