Couple Questions

I have a 01 GT Vert and I'm looking to upgrade the exhaust note my car makes at idle. I have the Magnaflow Magnapacks on right now and I love how they sound at WOT but idle they're too quiet for my tastes.
I want my car to sound like this at idle: http://youtube.com/watch?v=BWx-XeaNMaY.

I know I'm going to need some aggressive cams, heads, longtubes, and a nice midpipe (thinking of prochamber) and I want to stick with the cats I have now.

1. First question is I'm looking at the the Crower Stage 3 and 4 Cams. They say rough idle for the stage 4 and "lope at idle" for stage 3. What exactly does "rough idle" and "lope" mean?

2. Also, it says the rpm range will be 2000-6900 for stage 3 and 2250-7000+ for stage 4. Does that mean I'll need to get some sort of device that makes it so that in order not to stall out I need to be at 2000+ rpms at all times?

3. If I do end up going with the stage 3 or 4 cams what other things are required besides new valve springs?

Thanks in advance
