I want to allow my Swedish Ivy plants to climb up the wall and along the edge of the ceiling all around the room. Is this possible? What are the best ways to secure the stems?
I don't know of anything right off but perhaps you could try lattice, wire, or hooks.
What is the name of a trailing, scallop-shaped leaved (all green, no variegation) plant commonly known as 'Swedish ivy'? This was not the plant I thought it was.
Plectranthus verticillatus Syn. Plectranthus nummularius, Swedish ivy, Swedish Begonia or Whorled Plectranthus

How often should I feed my plants (Swedish Ivy) Miracle Gro during the winter months inside? I water them 2 times a week.
On average, these plants don't really need to be fertilized more than twice a month during their active growth, and hardly at all in fall or winter - no more than once, if necessary. Also, rather than water twice weekly, check the soil first and water only if it's dry to the touch.

I mist my Swedish Ivy daily between waterings. Should I include or use some spray and grow with some of my mistings?
I believe that everyone finds their own best way to take care of their plants. However, you might be interested to know that scientifically speaking, misting doesn't help your plants. Misting only raises the humidity around the plant a few percentage points, and that for only a few minutes. For misting to have any value in raising humidity, it has to be done every 15 minutes.
So if you enjoy misting your plant(s), go ahead, but know that you don't have to do it.
Secondly, for "spray and grow," I presume you mean some kind of foliar fertilizer. I don't think it's of any value to Swedish ivy; introducing unneeded minerals into (or onto) the plant can actually be harmful. Swedish ivy is a very undemanding plant. By far the most important factor in having a healthy plant is testing the soil moisture before watering, to make sure it's not too wet. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm
