I very strongly support the idea of putting in swales, ponds, etc first.

Wait, learn and listen.
The most important thing is to be patient and learn what your land has to tell you.
Spend time in all the areas of your land at various times of the year. Feel the wind. Look for the insects and wildlife. What are the native species already doing? What is the soil like in different areas.
Observe, take notes. Don't rush!
