Need a little help with the commercial pilot chkri

I'm having trouble passing segment #2 of the Commericial Pilot checkride.
1st Question: Immediately after the take off at Bremerton, you climb to 5500 ft. Then descend. Then climb to 6500 ft; then descend again. So just what is the point of doing these two descends? I already know that you're supposed to "keep the prop on top" and how to control the RPM and MP. I UNDERSTAND THAT CONCEPT ALREADY - WHY DEMONSTRATE IT TWICE?
2nd Question: One of the areas that I fail in is that the examiner claims that I did not lower my landing gears on descent. It can't be during my landing at Harvey airfield, because I have no problems with that part.
I'm guessing she's referring to the "gear down" descent??? Is that the part where you descend 6500 ft to 3500 ft? Well how the hell am I supposed to lower the gears if the plane is descending at 160-170 KIAS? That's well past the limit of 152 KIAS!
3rd Question: When you're approaching Harvey airfield at 1400 ft, she says to make left traffic pattern and then descend to 1018 ft when you deem appropriate (I'm basically paraphrasing her words). So is there a specific moment you're supposed to do that? During the downwind leg or final approach at Harvey? Or does it make any difference?
Last Question: What does KIAS and KIAT stand for?
I've gone through the entire commercial pilot flight lessons and it never explains the acronyms. I've even looked through the glossary section and it never mentions what these two acronyms stand for. Or have I missed something? I have many positive things to say about MS FS2004, but the flight lessons by Rod (IMHO) was poorly done! He should have atleast explained these important terms during the 1st flight lesson in the Barron or during ground school. And don't get me started on his god-awful cheeseball humour. His jokes in the ground school lessons are sophormic and childish.
