"Bicycling the Pacific Coast" by Vicky Spring and Tom Kirkendall is the standard reference. In addition, the Adventure Cycling Association sells good, if pricey, maps of the coast. As Niles mentions, wind will be blowing from north to south at that time of year. An ideal trip might be to ride south along the coast for 5-6 days, then hop on Amtrak for the ride back. You can probably ride from San Francisco to San Luis Obispo in 5 or 6 days, riding about 50 miles/day on average. A decent amount of climbing to get through Big Sur, though.
Another option would be to ride out and back. Winds pick-up later in the day, so you'd want to start early on the return trip and maybe plan to stop earlier. San Francisco to Monterey or Carmel might be one possibility. Ride from SF to Santa Cruz on the first day, then down to Monterey or Carmel on the second; you'll have a nice tail-wind at your back. Include an extra stop or two on the return trip, say at
Costanoa, Half Moon Bay, Butano State Park, or one of the other parks/towns along the coast. If you find that the wind is too much, you can alwasy climb over the Santa Cruz mountains, coast down the hill to Cal-Train and get home that way.
