Good news that the weather is going to miss you, Rosie. But if there is another storm or two before spring really settles in, you should consider mulching your new roses heavily with a good organic mulch. Do not use rock or rubber! It will not only keep the roots warmer and regulate moisture, if you pile it up around the stems a bit (remove it from touching the stems later) it will protect them from moving around in the high winds too. Come summer, the mulch will help again with moisture in the soil, preventing weeds and keeping the soil cooler - the sun can't bake it directly.
The basics of consistent nutrition (a good timed-release fertilizer) and watering (water the soil, not the foliage, always water in the morning, increase as the weather warms) you probably already know. Good air flow around and between your rose bushes is very important to preventing leaf fungus diseases like black spot and powdery mildew, so try not to crowd other plants around your roses.
If you're a beginner or novice with roses, we do have a whole dedicated forum here on ATP for roses.
http://garden.org/forums/view/... A wealth of info is available there, and all the current rose fanatics hang out there, too. (I used to live in Utah and grow lots of roses, but they are a challenge here in FL)
