Just caught up with this topic, did exactly the same myself...and yes got SFX pads, also got the 4" spot pads and 3.5" backing plate, good for getting in areas where the 6" cannt. Autopia are ace, nothing is to much trouble and they will still e mail you after to ensure that you got your order and everything is OK.
I did the scooby the other weekend with the PC, stunning finish if I say so myself the car just gleams like glass. I was experimenting a bit so went a bit over the top......practice on the scoob befor I attack the 350!! so this is what I did........AS a word of advice, always start with the least abrasive pad and polish first then work your way up, and ideally you need 2 or 3 pads of each grade.
Washed car 2 bucket method with lambswool mit & Maguires NXT wash
Dry with waffle weave towel
Clayed car with Meguires claybar and quick detailer as lubricant
Wash & rinse & dry car.
Inspect swirls & condition using 500w interior lights & get machine out of box!
Tried SFX blue 6" pad with poorboys SSR1 which had no real effect on the swirls, so ended up using SFX yellow pad and SSR2.5 buffed off with microfibre towel.

Poorboys Exp sealant applied over by hand and left for about an hour to cure and buffed off by hand and finished that off with a 3 coats of Nattys blue paste wax. 12 hours between applications.
The wheels were polished with AG srp polish and EXP sealant then waxed with nattys blue (not the best wax for wheels but all I had) and the tyres were dresses with Autoglym tyre spray.
All glass was cleaned both sides with meguires fast glass applied with kitchen paper and buffed of with microfibre towel. Little trick in cleaning glass I found is if you clean the outside with vertical strokes and the inside with horizontal strokes, you can see if you have missed any areas easily or havent buffed some off.
Exhaust stainless was polished with Solvo autosol.
I'm not really an anorak ...but having experimented I now know the easy way forward for the zed.
