We have four tomatoe plants in the greenhouse and two of them have brown stains on their lower leaves and also some leaf curl. Is this because of the very hot temperatures we have experienced in the greenhouse this year. This is our first year with a greenhouse.
It is likely due to the humidity in there. Sounds like a fungal infection. I would need a photo to be sure, and to give you proper advice on a solution to the problem.

we have tomato plants that tend to get very tall(one year they were over 8'tall) but don't seem to have a high yield. What can we do so the plants produce more fruit and don't get so tall?

My plants looks funny
Yes, it does! There is a pH issue. Add dolomitic lime and wettable sulfur according to the instructions on the package. I could bore you with the details, but these two items will keep gardening pretty carefree and easy. This can be, very easily, corrected given that you act fast upon this.
Two weeks ago I purchased and planted a tomato plant about 18" tall. It had a small tomato on it then. My question is since that tomato is obviously premature is it stunting the growth of my plant. If so what should I do about it. Just so you know it is planted in a raised bed garden. Thanks
Yes, you can remove that early tomato to give the plant a chance to set good roots.

I have a sweet 100 tomato plant in a container. I've noticed spotty, yellowing leaves for a week or so - also, the foliage seems sparse (although there are lots of tomatoes). I have attached photos of the leaves and of the entire plant. I'd really appreciate any advice as to what might be the problem, and how to address it. Thanks!
What kind of soil are you using? It looks somewhat compacted. It looks like the start of an infection. This can be corrected using wettable sulfur and dolomitic lime. I would also give it a tomato fertilizer every few weeks, as well. This will keep it producing and healthy.
