I have several sedums growing in my flower beds now and was wondering when is a good time to divide them? I also saw where you can just put a stem in the ground and it should grow. Is that correct?

Wait until after the first frost and then cut the plant back to about a couple inches. Apply a fair amount of straw mulch to keep it well protected over winter. You can also choose to leave your sedum plants alone until spring (trimming back the same amount), allowing the foliage to provide the plant with winter protection.
How do you care for autumn sedum during winter?
Many people cut them to the ground this time of year. These plants have a hard time surviving the winter so you can expect about a 50/50 chance of them surviving regardless of what you do. However, you can take steps in order to protect them over winter. This article will help with that: https://www.gardeningknowhow.com/ornamental/flowers/chrysanthemum/wintering-mums.htm

This summer I planted a stonecrop orpin silver frost plant. It is a low lying plant and spreads very rapidly. I have noticed it is spreading all over the place between all my other plants. If it grows between the other plants, it is OK, but what I want to know is if it will smother the other plants?
It should not hurt the other plants. Some sedums and stonecrops will form a mat but they just grow around established plants and bulbs have no problems growing up through it.
I've transplanted/divided many sedums mid season, but I don't think I've done so when in bloom. Is it best to cut off the bloom heads before transplanting, or can I just divide/transplant with the blooms on it?
You can still divide them (trimming the plant back), though it is normally better to wait until the blooming has ceased.
I have tall, gangly sedum. Is it too early to break it off for winter?
Most sedums do not need pruning, but if yours is getting unruly or unsightly, you can simply cut off unwanted growth with a sharp, clean pair of scissors.
