Welcome! No, your story was not too long. You seem to be off to a good start.
Try to get up from your desk once an hour, if you don't already. You don't have to do a lot, but more than just standing up.
80% is ok. 90% is fine. Don't worry about being perfect. You should probably stick to one drink or less/day.
Dairy is fine if your body can handle it and it doesn't hold you back. I consume a fair amount and am losing fat.
I eat a fair number of organic corn tortillas but they are definitely not primal.
