1. Exactly what are you keeping track of? Each day's blood glucose readings, and

then their average? Unless you are testing a lot, an average of those readings may not give you a number that reflects your actual A1C. My doc uses my A1C (which his lab does on me every 3 months) and he flips through my record book to see a sampling of my daily readings over the last month or so.

If you want to keep a record on your computer, use an Excel spreadsheet. You can record your readings, and you can add them up and average them using an Excel formula. Then there are tables on the internet that can tell you what your average reading is as an A1C number. It's quite easy.
