I have a brand new USB 3.0 4-port hub and also I have a new Seagate Backup Plus Drive as my new external hard drive.Thank you so much for the recommendations !!!!!!
I ordered a second Seagate Backup Plus Drive, so the new one that I have now which is in classic black (while I'm waiting for the second backup, which will be in royal blue, to be delivered) will be dedicated to Time Machine.
Hooray! My new one shows up on my desktop!
Now what do I do?

? Baby steps and pictures help, as some of you know only too well...without them, I kinda flail.
How important is the "Start Here Mac" icon that shows up when I double-click my new Seagate icon?
Here are some screenshots...
