Blue I would listen to Anthony here...
It seems like you have the LC CCS pads... white and orange is enough to start out with, and you might want yellow for some tougher jobs later on, but first you should get used to the milder polishes/pads...
Looking at the first pic you posted, of the swirls, I would've personally chosen the orange pad with OC instead of OP... OC with orange takes those swirls out easily from what I've experienced, and leaves the paint pretty nice, but not LSP ready....
Next step after OC/orange would be OP on a white pad... that, for me, finishes down LSP ready almost all the time, but like anthony said, there's just something about OP on some vehicles, usually darker, that leaves you wanting more... Menzerna FPII finishes down nicer than OP with a white pad IMO...
Next, either choose a glaze on a white pad, something like Meg's #3, and that should get the paint ready for LSP...
I'm writing all this from experience though, so of course not everyone will get the same results...
That said, I think you should've started (and do so from now on until you get a feel for different cars, colors and pad/polish combos) with something like FPII or OP on a white pad...
if you see half or more of the swirling gone, give it a 2nd pass with the same combo... you don't necessarily need to step up the abrasiveness just because you didn't remove all the defects with 1 pass...
ideally, you would go over the car 5-6 times with a polish such as FPII on a white pad and be done, but in reality, that takes too long... so to save time, you find the worst area on the car, and try out 3-5 different polish/pad combos to see how it goes... this is where you need to start with FPII and white pad, then move up, and back down in abrasiveness, whether it's with pads or polishes (I prefer altering the abrasiveness with polishes)
lastly, the holograms in the photo after you went over with OP/orange are most likely caused by too much product or user error... don't go too fast, don't go too slow, and I would suggest putting a couple lines in between the grooves on those pads, instead of big blotches like that... oh and might want to try out the 6.5" CCS pads... I use the 7.5" about 5% of the time, rotary or RO
Sorry for the long post... hope it helps though
