Are these pants good for everyday office wear?

Yes. The straight cut, flat front and pressed crease read formal enough for most offices, and the wool holds its shape through a workday. They are dressier than chinos or cotton-blend trousers.

How do they compare with Prada's other trousers?

These are the more structured, formal option. Prada also makes softer, more relaxed trousers and technical-fabric styles, which suit casual wear better but look less sharp with a jacket.

Do they run true to size?

Prada tailoring generally runs close to standard Italian sizing, which is trimmer than US sizing. Try your usual size first, and size up if you are between sizes or want a looser leg.

Can the pants be machine washed?

No. Wool tailoring like this is dry-clean only. Machine washing risks shrinkage, felting and loss of the crease.

What should I wear them with?

A blazer and leather shoes for formal settings, or a knit and loafers for smart casual. The plain black wool pairs with almost anything in a tailored wardrobe.

Are they worth it over a cheaper wool trouser?

The value is in the wool quality, the cut and the finishing, which hold up better over years than most mass-market wool trousers. If you want a single hard-wearing formal pant, they make sense; for occasional wear, cheaper options are fine.
