Note: when I lead a bilingual worship service, I usually find it best to lead one portion in English, then the following portion in Spanish, and so on. Meanwhile, people follow along in their bilingual order of service. If you try to repeat everything in both languages, the service gets to be way too long, and people are often distracted and not focused on worship.
