Yes, ∗most likely∗ they are in uF, as in 0.001uF and 1.0uF
The 0.001uF will be nonpolar; the 1.0uF might me either depending on what
type you specify. Most likely it's a polyester film cap and will be
nonpolar.
Your enthusiasm is good, but with these questions, you might want to ask for
someone more experienced than you to check your work.
