Hey guys!
I just started getting into Chia. I was looking for some help on plotting efficiently.
My Rig  Intel Core i910900 10Core 20Thread Desktop Processor, 64 GB RAM (3200Mhz), 1TB NVME SSD (for plotting, this is temporary, i’m getting another 3.84 TB enterprise SSD in the mail which will replace this), 6TB Internal HDD, 2 x 12TB external HDD, and 2 x 10TB external HDDs.
I have the following questions:

How do I calculate the number of plots it will take for me to fill up the 6TB, 12TB and 10TB drives? Since each written plot is ~108.9 GiB, would it be ~49 plots to fill the 6TB, ~100 plots to fill the 12TB drives? If my calculation is wrong, can someone please point me in the right direction?

How do I parallel plot efficiently using k=32. How many plots can I run parallelly? Since each plot takes 4GB RAM, 2 cores and about 250GB of space? Can i only run 3 plots at a time (since I am SSD restricted at the moment)? If so, once I get 3.84TB drive, how many plots can I run parallelly taking advantage of the 10 core CPU and 64GB RAM? Is there a step by step on how to set this up? For example: what values to set in advanced? Do I select parallel plotting or adding to a queue? What is the delay that I should set? I keep getting confused here so if someone can ELI5 here, I’d truly appreciate it!

Once I fill up all the HDDs that I have and once they are all farming, is that it unless I expand my storage?
