Starting with 200 grit is going to take ages and a lot of paper to get 1.25mm off.
Yes & No. I start much lower. But I am very used to power sanders and how to use them, I do a pass at 60 then 80 then 120 then 200. this takes care of all deep areas and smooths out the surface. Having said that if it’s only a bit of surface crazing 200 is more than adequate as you do not want to "dig " into the material.
As for the paper, when you use sanding paper, there are Blocks of Rubber to clean the sanding paper which should be used often. Screwfix sells them for instance.
You just run the sander on it.
