High Relative Humidity in New Construction House
I live in Seattle (currently 60 degrees, 87%RH) and have just moved into my new construction house - RH 70%. Through the construction process, I have introduced a lot of moisture into the home - damp cellulose insulation, suspended concrete slabs main and second floor, full basement (properly waterproofed with exterior/interior drainage/sump with upslope curtain drain and tightlined downspouts), textured drywall and paint.
Reading this site, I read M Holidays article which suggested I may be adding more moisture into the house by my use of a HRV- since the RH outside is higher than inside.
My current strategy to lower the RH is to keep spot fans running in all bathrooms, run a dehumidifier in the basement, run the HRV on low...and limit the kids and dog to ... marginal mayhem.
What other strategies are recommended? Also, are there quality dehumidifiers where I can tackle high RH while minimizing an energy penalty?

Is it OK to step the slab thickness over the footings to accommodate insulation between the slab and the footings?
Can construction foot traffic on the roof dislodge or break the seal between the foam and the sheathing?
