Wantbuck,
Everyone that has given you instructions is correct. You'll find that some people have their own way to doing things...not wrong just different. (Now for my 2 cents worth) As far as the anus is concerned, cut the pelvis bone (slowly and carefully) and you'll have exposed the anus. Grab a hold of the anus and cut it free. Once it's free, get all of the gut out of the deer and wash it out as soon as you can. Try to keep leaves, mud, and the likes out of the cavity.
