"Residence" means where you dwell and "presence" means where you are during the period in question. You may "reside" in the US, even though you may have departed for short periods. Please consult with an immigration attorney for additional information.
Generally the more documents the better. Physical presence is actually being in the US without an absence. Continuous presence means physical presence with short incidental trips abroad. In addition to utility bills, tax returns, bank statements and leases are good evidence.
