I live in WYO. I get bedding plants at the nursery as our growing season is very short. Last year I got some red bell peppers and they never turned red. Any advice?
Time to maturity (how long they take to become their full ripe color) can vary from 60 days to 120 days, depending on the variety. This article should help: https://www.gardeningknowhow.com/edible/vegetables/pepper/how-to-grow-red-peppers.htm
Is it normal for the flowers and their stems to fall off of the plants or is something wrong?

I planted red bell pepper plants and they seem to be healthy except every time there is a bloom, something seems to be eating the stem about halfway between the plant and the bloom. What could be eating just that part of the plant?
I do not believe it is any type of pest. It's possible that the plants may be dropping the blossoms. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/pepper/pepper-blossoms-falling-off.htm
The largest of the peppers was about 2 inches and had good color, then after a couple of days we noticed that our young red peppers had brown spots. It looks like the skin had died. What do we do to fix this and what is it?
If the spots are on the top or sides of the fruit, then it is likely sunscald and is from too much direct sunlight. A simple shade will help stop it. If they are on the bottom of the fruit, then it is blossom end rot. These articles will help: https://www.gardeningknowhow.com/edible/vegetables/pepper/pepper-sunscald.htm

I just recently harvested my first red bell pepper and was looking forward to eating and enjoying it. It was smaller than the ones I'm used to getting at the store, but it was bright red. When I cut it open, I noticed that the seeds were very tiny and black. I was dicing it to put in a recipe, and decided to taste a bit and was very surprised at how bitter and horrible it was. No sweetness whatsoever! The plant is producing more peppers. Is there something that I can do to prevent more peppers like this?
Make sure the plants are getting enough moisture and nutrients. A 5-5-5 fertilizer will help. No more than 8-8-8.
I know you can freeze them, but then you can only use them to cook with. I want to keep them fresh as long as possible.
I've been able to keep uncut green peppers for about two weeks - keep them in the fridge, unwashed, in the crisper part of your fridge. Sometimes sealing them in ziplock type freezer bags (not the lite-weight sandwich types) from which you have expelled all the air before sealing will help them to keep longer.Keep freshly harvested vegetables/fruit separate from the ones that have been cut. Reds probably won't keep as long as they are actually a more mature fruit to begin with.
Why are some of my peppers rotting on the plant before they turn red?
It may be blossom end rot. This article will explain more and how to fix it:
