Yes, best to have the clutch surface machined before you install the new clutch.

best to machine it by a shop. if you dont feel like doing that, take some 180 grit sandpaper and make the surface matte.

+1 on having the surface re-ground. If you hadn't been slipping it would have almost certainly been fine.

You can have a SMFW resurfaced. Unfortunately nobody hear knows the condition of it without looking at it. Just expect to resurface it and if you're lucky and it looks in good condition with no hot spots or abnormal wear then you can reuse it.
