Don't sweat the details, by the end of one week it will be almost second nature to you. You have to shift so many times in one trip, and how many times will you drive the car in your first week of ownership; probably lots.
The obvious is don't red line it. There is no "rules" for shifting, you'll want high revs when passing, etc. You'll want low revs some of the time when you don't want to "labour" your engine.
In snow try using second or third gear if you get stuck, not first - too easy to spin your wheels.
For passing at highway speeds, you might want to downshift one gear first before the pass, especially if you are in fifth gear. Depending on speed, you might even want to downshift two gears, if you need a quick leap forward, then quickly shift into the next gear.
Oh, and don't spill the coffee when you're shifting, very important rule.
