I ripped off my old roof and got it ready for laying the new shingles. I
planned on starting with a whole shingle, next course -4 inches, next
course -8. Then back to the full shingle.

With the 3/8 inch overhang required, each row of shingles is 24 feet and
7/8 inches. If I use full shingles, I come up 7/8 of an inch short at
the end of the row. Should I just allow a bit of space between each
shingle to make up the 7/8 of an inch over the 24 foot run or???

I would go with "or". Lay your starter about 8 inches past the rake,
then first shingle 2 inches over the rake edge, go up to the peak, and
temporarily tack another shingle 2 inches over the rake also. Snap a
chalkline on the decking from the end of the top shingle to the end of
the bottom shingle. About 6 inches in from where you just snapped a
line, you'll see a notch or slit at the top edge of each shingle. Snap
another line between these notches from top to bottom. Use both chalk
lines carefully to line up vertically the right edges of your first
run-up to the peak. Stop every 5 shingles to lay a guide shingle along
the rake at your desired overhang, and with a sharp hook knife, trim
your rake. Save your cut-offs to fill in the other rake edge. Tom
