Full disclosure, this is my first time replacing a toilet but it looked easy enough so I figured I could handle it. Now that I've got the old toilet removed I'm not so sure. The metal part of the flange is two pieces, but I'm not sure how the plastic part of the flange attaches to the soil pipe. I figure this flange has to be replaced, but I'm not sure how involved that will be. There is still one closet bolt to remove - it's soaking in PB blaster right now. So is this a fairly easy job that I should be able to handle or is it time for a professional? Here are a couple pics of the flange:
