Hit it with 800 wet and dry, being extra careful of your edges. If it helps run some 12mm masking tape over your ridges to stop you sanding too close (or through) to them. You just want to form a key for the clear.

Same difference whether it's metallic or solid colour. The main reason for colour sanding before applying clear is to smooth out any orange peel ,runs etc so you get a smoother glossier deeper looking finish.
Adhesion should not be issue if you apply acrylic clear coats over acrylic colour that has already dried.
Acrylic lacquer thinners are referred to as hot thinners as they melt into the previous/existing paint layers as you apply the next coat.
That is why it is not advisable to spray acrylic lacquer over enamel as the lacquer thinners will soften the enamel and make it wrinkle, blister and peel.
Enamel thinners on the other hand are referred to as cold thinners as they don't melt into the previous/existing layers.
Enamel can usually be sprayed over acrylic lacquer without any major problems.
Mixing some top coat colour in with the clear is usually done when repairing metallic paints and you need to blend the new paint into the existing. It should not be necessary to mix some top coat colour with the clear coats when doing a full repaint but no reason why you can't if you want to.
