Beginner Gardening: Please help with begonias., 1 by HiImMel

Wanting to help out the bees, I decided to get some flowers.
Too late to plant now, right? So, thought I should just get some already grown flowers instead for now.
So, while at Walmart today, I found a couple pots of begonias on clearance. They’re not in super awesome shape, but they had more flowers than most of the other plants. Couldn’t find anything native, but hoping they’re a bit too sensitive to become invasive in my area. (Any insight on that? I live in the middle of South Carolina. Growing zone 8a. Lots of clay in the dirt where I live.) ✅

I have a few questions for anybody who would be willing to help me with any of them:
What kind of begonias are these? ✅
Do these transplant well? I kind of want to switch them to different soil, I would guess that from a normal store the soil would have pesticides in it, right?
You can see in the pictures that some other flowers have already died. Will these continue to flower until it gets too cold?
What should I do to care for them at this point? As you can see there are some dead flowers still attached, should I leave these here to collect seeds that they will produce? Or should I cut them off? How about the damaged leaves? Anything else I should do to these plants to make them healthier now?
Is saving seed from these to plant next year possible? ✅ For example, are these easy to grow from seed? And is there anything special about collecting them storing seed from this plant that I should know?

Thank you for any help you can give. I know there are a lot of questions here, but I really appreciate anything you can contribute!
