@davidj77, a few points of advice:
For the fermentation process, the 1-3-3 rule may help. 1 week for fermentation, 3 weeks to clear, and 3 months of bulk aging before bottling.
This schedule varies, as fermentation time is variable. If you don't have a hydrometer, get one, as it's the one guaranteed way to know that fermentation is complete.
Once fermentation is done, I started the habit of stirring the wine to degas. Stir for 30 seconds, then change direction for 30 seconds. Repeat this twice for a total of 3 minutes. This does not drive off all CO2, but it accelerates the natural degassing process.
Why degas? CO2 holds sediment in suspension, and the wine clears much faster with the CO2 gone, or at least greatly reduced.
The gross lees (mostly fruit solids) will drop relatively quickly. The rule says "3 weeks" but you'll see sediment build up, then the level reduces as the lees compacts. At that point, you can rack, add K-meta, and bulk age for at least 3 months.
Backsweetening? You'll need to stabilize with potassium sorbate and K-meta. Sorbate does not stop a fermentation, but prevents a renewed fermentation. If you stabilize, you can backsweeten to taste. If you don't stabilize, the yeast will start eating the sugar and you get more fermentation.
You want sparkling? Use the method home brewers use. First, do NOT stabilize the wine. The wine must be dry.
Add 1/2 to 3/4 cup per 5 gallons and stir well. For smaller batches, do the math to figure out how much sugar to add. 1/2 cup is 24 tsp, and 3/4 cup is 36 tsp. If making a 1 gallon batch, divide by 5, so you're using 5 tsp to 7 tsp.
Put the wine in beer or champagne bottles, and crown cap. Place the bottles in a warm place (70 F minimum) for at least 2 week. The yeast will eat the little bit of new sugar and produce CO2, which dissolves into the wine.
DO NOT use screw cap bottles or regular wine bottles. These bottles are not built to handle pressure and can explode. If using a cork, the bottle won't explode, but the cork will blow and you will have mini-volcanos and a mess to clean up.
