Narrative:
After receiving a clearance to 'descend via seavu arrival cleared for the approach; maintain 280 knots' the captain didn't set MCP altitude and I failed to catch it. ATC called us back in approximately two minutes and asked if we had started down. We realized the mistake and attempted to comply with the clearance but slowed below assigned airspeed due to VNAV built in speed reduction; which we corrected immediately after which we received no further word from the controller. There were no altitude busts; just a slight reduction below assigned speed. The arrival had been briefed thoroughly for what we expected and what was given. Event was simply a mistake we attributed to unfamiliar new MCP procedures. A contributing factor was a heavier than usual workload environment due to monitoring fuel management to avoid an over weight landing. We tankered fuel from iah. We requested a lower altitude at approximately phx to comply with landing weight.
