Re: I got my stuff/ couple questions
The 7424 comes with the 5" counter weight... some have reported experiencing less vibrations and more spinning (of the pad) after purchasing the 6" counterweight, others have reported no significant difference. It's absolutely ok to use the 6.5" pads with the 5" weight.
Can you use the white pad on the headlights??? Sure, you can try, it won't hurt anything but I can't speak from experience regarind how well it work.
Scared of the PC... yep, almost everyone is at first, I know I was, but the truth is, there's no reason to be, just use the smallest amount of common sense and you'll be fine. Seriously, when you read these forums and haven't tried it yet, you hear people talking about this polish or pad being "agressive" and it sounds really scary. You'll find out that using the pc to remove swirls, while doable and rewarding takes quite a bit of time... which is good, because it would take that much longer to do real damage.
