Not much difference in the way they work. Just remove the adapter, back off the knurled knob at the top of the presta valve, replace the adapter and use the pump the way you always have. After inflating the tire, remove the pump, remove the adapter, tighten the knurled knob again and replace the valve cap or adapter. Ride away.

If you really prefer schraeder valves on tubes, you can always carefully drill out the hole to accommodate the schraeder valve. It has negligible effect on the strength of the rim. If you stay with the presta valve, do what I do and buy a few tubes ahead of time so that you have them on hand when you need them.
