Are scales and arpeggios important in Baroque music?

Of course, the scales are used as a bridge to the new melody in fugues for example, or just as the main. The arpeggiOS are important to ornament the melody; often used in church organ, as a decorative way of phrasing.

The baroque period is remarkable in virtuosism terms, it's the principal characteristic, as like as complex harmony and melodies, with a great contrapuntistic coordination.
