I like the Yukon Golds as well as the Pontiac Reds, and have planted both this year. I'll be adding Beauregard Sweet Potatoes this week.
The key to planting them is to ensure an acidic soil to avoid scab, and to either hill the individual plants once they get about 8-12" tall, or use some type of mulch. The object is to keep the tuber from breaching, and becoming exposed to sunlight, as they can become slightly toxic if allowed to do so. Once the blooms emerge and the plant dies, allow the tubers to remain in the soil for up to two weeks so that the skins will harden up. They will continue to grow somewhat after that, and will be perfectly fine unless you get alot of rain. Should that occur, harvest them or they will rot, especially if you have a clay soil. Sweet potatoes will continue to grow until first frost takes the vine, but I usually harvest mine in late August, or four months after planting. Your area may be different in frost cycles.
Once harvested, clean them off and allow them to dry, then store them in a container that allows air to circulate in a temp between 50* and 70*. We use a wicker basket with clean straw for the container, and our garage/basement remains at 68* year round, so it works out.
Good luck with your endeavors, as fresh home grown vegetables beat the store bought stuff every time.
