1) Depth of concrete is a no brainer. Drill a hole then measure thickness.

2) I recommend you have 2 hammer drills. One smaller one with a 1/4" x 6" bit and a 30#-40# hammer drill for the actual hole size needed. Lay out where you want it to sit and mark the holes. Now take the small hammer drill with a 1/4" bit and drill center of each hole. If it stops penetrating pull the bit out and check for grey dust. If you see grey dust you're on rebar or post tension steel. Drill all 8 holes then determine where and how many spots have steel beneath them. If none, Bingo. But more than likely you will hit at least one piece of steel and then you will need to shift the location of the holes an amount that will get you in the clear. Before shifting the hole locations only to find out that you've ended up upon another piece of steel do this. Using one of the 1/4" holes as a starting point drill another hole at a slight angle. If it clears then you know where the steel is and isn't thus preventing a Swiss cheese effect in your slab. If it turns out that you can't relocate w/o being on top of a piece of steel then you can have one or 2 anchors installed on a slight angle. You will need no make a washer that is beveled so that you can tighten the bolt w/o having the edges of the bolt head strike the plate preventing you from tightening the anchor completely.

3) They ship 8 anchors and no spares so take your time. Those anchors aren't going to be at your local hardware store and they're pricey to boot. If any of the local boys want to install one feel free to borrow my big hammer drill. (IMG:style_emoticons/default/beerchug.gif)
